Soccer, Hoops Next to Seed Using MPR
August 6, 2019

As the topic of seeding for MHSAA Tournaments continues to swirl in the air of numerous committee meetings on an annual basis, one of the primary concerns continues to focus on the simple question: “How?”
The MHSAA for years has been working behind the scenes on potential formulas which could best be used as a standardized tool to assist in measuring strengths of teams in a given sport.
This spring, the MHSAA introduced the Michigan Power Rating in the sport of Boys Lacrosse. The Representative Council approved limited seeding beginning in 2019-20 for girls and boys soccer and girls and boys basketball, and MPR will be the metric to determine which two teams must be seeded on opposite sides of District brackets in those sports.
“The boys lacrosse tournament has been seeded since it was added as an MHSAA-sponsored sport in 2005. The seeding is done by committee based on several criteria, one of which was statewide power rankings generated by a third-party website. In the Fall of 2018, that website ceased operation – it was the perfect opportunity for the MHSAA to develop its own data-driven, purely objective ratings system and incorporate that data into the seeding criteria,” said Cole Malatinsky, administrative assistant for the sport.
“The benefits of the new MPR system have been already mentioned – it is MHSAA controlled, simple, objective, and transparent, and it can be used by other MHSAA sports in the future.”
MPR is a computer rating formula similar to the popular RPI rating. MPR provides a way to measure a team’s strength relative to other teams, based on games played against other MHSAA tournament teams, largely on the strength of their opponents’ schedules. MPR is purely objective using only the game results listed on MHSAA.com – there is no subjective human element.
What is the basic MPR formula?
MPR is calculated using wins, losses and ties for games played between teams entered into the MHSAA tournament. The final MPR number is 25% of the team's winning percentage, plus 50% of its opponent's winning percentage, plus 25% of its opponent's opponent's winning percentage.
MPR = (.25 x W%) + (.50 x OW%) + (.25 x OOW%)
The MPR formula can be applied easily to other MHSAA team sports.
What game data is included in the formula? What game data is not?
MPR looks only at results between opponents entered into the MHSAA postseason tournament. Wins, losses and ties in multi-team shortened game tournaments (lacrosse, soccer) also count. Forfeits also are counted as wins and losses.
MPR does not use the specific scores of a game or the margin of victory in a game. The location of a game is not included in the MPR formula, and the formula weighs results at the beginning of the season the same as results at the end of the season. Scrimmages are not included.
Why use the MPR formula?
Different rating systems have been used in the past or have been recommended to the MHSAA. We wanted to have a rating system where the data was controlled and stored in house and could be used for any sport featuring head-to-head competitions.
With its own rating system the MHSAA also can control the different components of the formula, thus keeping the tenets of scholastic competition at the forefront (like not including margin of victory in the formula). Finally, by listing all scores and team schedules online, as well as showing the MPR calculator on each team schedule page, the ratings are transparent and can be replicated easily.
CALCULATING MPR
What are the detailed components of the MPR formula?
You need three numbers to calculate your MPR: winning percentage (W%), opponent’s winning percentage (OW%) and opponent’s opponent’s winning percentage (OOW%).
How do you calculate winning percentage (W%)?
Divide the number of wins by the number of total games played. A tie is worth half a win. For MPR purposes, find the winning percentage against all teams that will play in the MHSAA tournament (MPR W%). Games played against out-of-state teams, varsity “B” teams, junior varsity teams, non-school club teams, and any other non-MHSAA tournament participants should not be included when calculating winning percentage. W% should be an easy number to calculate.
How do you calculate opponent’s winning percentage (OW%)?
Average the winning percentages of a team's opponents. When calculating the winning percentage of a specific opponent, use the opponents "Adjusted Winning Percentage" (ADJ W%). Adjusted winning percentage eliminates all games the team played against that opponent (as well as its games against non-MHSAA opponents).
For instance, if the team beat an opponent with an overall record of 4-1, use a record of 4-0 (1.000) for that opponent. If the team lost to an opponent, use a record of 3-1 (.750). Find the ADJ W% for all opponents, and then take the average. If a team plays an opponent team twice, that opponent’s ADJ W% will be counted twice.
OW% is not calculated via the combined record of the opponents; instead take the average of all opponent’s winning percentages.
How do you calculate opponent’s opponent’s winning percentage (OOW%)?
Use the same process described above, except calculated for the opponents of a team's opponents. This number is much harder to manually calculate, so the OW% for every team is listed on the MPR page of the MHSAA website.
Again, simply take the average of all opponent’s OW%.
How often is MPR calculated?
MPR is calculated about every five minutes. Enter a score and a minutes later the team MPR and the MPR of all the team's opponents will update.
How much will my MPR change throughout the season?
You will see wild MPR swings in the beginning of the season, but after about 10 games played your MPR will start to level out. At 20 games played you will see very little movement with each additional game played.
My score is missing. How can it be added?
This is a crowd-sourced system. Any registered user of MHSAA.com can add a missing score. ADs, coaches, parents, students and fans all can login and enter a score for any game.
What are some common errors when calculating MPR?
When calculating your team’s winning percentage, only include games against MHSAA-tournament teams. When calculating your opponent’s winning percentage, don’t include the games they played against you. When calculating ties, count the game as a half-win and half-loss.
What happens if a game is cancelled?
Because the MPR system works off of averages, it will not make a difference in the final MPR if a game cannot be rescheduled. It would not penalize, nor benefit, any team involved in that scenario.
USING THE WEBSITE
Where can I find game scores?
A list of statewide scores for all sports can be found in the MHSAA Score Center. To find a schedule for any team click on “Schools & Schedules” in the top navigation bar, search for the school, then once on the school page click the sport. You can also see a list of all schools (with links to schedules), on the statewide MPR list.
“We continue to have great success in score reporting for varsity boys lacrosse contests. While we state that schedule submission and score reporting to MHSAA.com are required, athletic directors and coaches understand that in order for MPR data to be accurate, we need consistent and accurate score reporting,” said Malatinsky. “MHSAA.com is now the primary site for high school boys lacrosse schedules, results and ratings in the state.”
How should I use the statewide list of teams and MPR?
Linked to the boys soccer page (and eventually to be added for both basketball pages and girls soccer) is a statewide listing of all Michigan Power Ratings (MPR) for teams entered into the MHSAA postseason tournament for that sport. Linked on the MPR page is an explanation of the District draw formula, describing when and how teams will be placed on the bracket.
The MPR data updates every five minutes. Click on the column headings to sort the data. You also can use the drop-down menu to show teams in one Division, or type a District number in the box to filter teams for that District (Region for boys lacrosse).
You also can click on any school name to go to its schedule page.
How do I read the school schedule page?
The schedule at the top of the page shows the date and opponent for all scheduled games, and results for games already played. If results are missing, click “Submit Score” to add a game score.
Below the game schedule is the MPR Calculator. The calculator is split into three sections. The first section shows the three MPR component scores for the team, as well as the team’s current MPR score. The second section shows the MPR information for the team’s opponents – specifically, for the opponents the team already has played (actually, for games where scores have been submitted). Only these games are included in the MPR calculation.
The third section highlights future opponents. The MPR data for future opponents are not used in the MPR calculation for the team.

This month's girls basketball championships will once again cap the MHSAA winter tournament schedule, and nearly 670 teams will play in Districts this week with dreams of finishing this three-week run on the season's final day.
We always switch up our “Breslin Bound” format once the MHSAA Tournament starts, as last week’s most intriguing results below are followed this time by glances at three District brackets of note in each division. Host sites are bolded, and teams playing in those brackets are listed by seed as determined by Michigan Power Ratings (MPR).
Everything you could want to know this week about tickets, brackets and more can be found on the Girls Basketball page. To watch any of several games online, visit the NFHS Network.
“Breslin Bound” is powered by MI Student Aid and based on results and schedules posted for each school at MHSAA.com.
Week in Review
The countdown of last week’s five most intriguing results:
1. Howell 59, Belleville 51 The Highlanders (21-1) claimed the overall Kensington Lakes Activities Association title by handing reigning Division 1 champion Belleville (21-1) its first loss since Feb. 1, 2025, breaking the Tigers’ 35-game winning streak.
2. Grand Rapids South Christian 52, Rockford 50 The Sailors (22-0) capped a perfect regular-season run by handing the Rams (20-2) their first defeat since Dec. 16.
3. Morenci 39, Blissfield 38 The Tri-County Conference champions Bulldogs completed a 21-1 regular season by edging the Lenawee County Athletic Association-winning Royals (18-3).
4. Negaunee 41, Gladstone 36 Negaunee also capped its regular season at 21-1 by finishing a series sweep of Gladstone (18-4) in a matchup of two more league champs and arguably the best teams in the Upper Peninsula.
5. Beaverton 53, Standish-Sterling 29 Four days after defeating Standish-Sterling (17-4) by 11 in league play, the Beavers (19-2) claimed the overall Jack Pine Conference title by winning this rematch as well.
Districts at a Glance
These could be among our most competitive brackets. Host sites are in bold, and teams are listed by seed:
DIVISION 1
Midland
1. Midland (17-5), 2. Mount Pleasant (16-6), 3. Midland Dow (14-8), 4. Bay City Western (12-10), 5. Bay City Central (1-21).
This bracket includes the entire Saginaw Valley League North except for champion Saginaw Heritage. Midland finished second to the Hawks, a game back, with Mount Pleasant third although those two split their series, the Chemics winning 44-29 on Jan. 9 and the Oilers taking the rematch 48-41 on Feb. 10. Dow lost twice to both of those teams but only by a point to Mount Pleasant the second time.
Muskegon Mona Shores
1. Rockford (20-2), 2. Muskegon (19-2), 3. Cedar Springs (16-5), 4. Greenville (16-6), 5. Muskegon Mona Shores (12-10), 6. Muskegon Reeths-Puffer (12-9).
The Rams were Division 1 runners-up last season and have reached at least the Semifinals the last four year. But Muskegon is one of only two teams to defeat Rockford this winter, 58-51 on Dec. 16, and has made an eight-win jump from a year ago. This bracket also includes the River Cities Alliance champion (Cedar Springs) and runner-up (Greenville) among six teams all with winning records.
Utica Eisenhower
1. Utica Eisenhower (19-2), 2. Rochester Hills Stoney Creek (18-4), 3. Romeo (16-6), 4. Rochester (10-11), 5. Utica (4-18).
The District bracket is headlined by a pair of league champions – Eisenhower from the Macomb Area Conference Red and Stoney Creek after sharing the Oakland Activities Association Red title. But MAC White runner-up Romeo also is an intriguing contender despite a Dec. 19 loss to Eisenhower, 50-32, and Rochester defeated Stoney Creek 48-29 in their rematch just nine days ago. Eisenhower did also end the regular season with an impressive 50-44 win over Saginaw Valley League South champion Flint Powers Catholic.
DIVISION 2
Non-Traditional (top line hosts)
1. Negaunee (21-1), 2. Kingsford (15-5), 3. Gladstone (18-4), 4. Houghton (16-6), 5. Escanaba (2-17).
There’s an argument to be made that Negaunee and Gladstone – the respective champions of the Western Peninsula Athletic Conference and Great Northern Conference – have been the best in the Upper Peninsula this season. But the top four teams in this bracket are so close statistically that in the week since Districts were seeded Houghton has moved up to second in MPR and Kingsford down to fourth. Negaunee finished a regular-season sweep of Gladstone on Thursday, but last year did the same and Gladstone downed the Miners for the District title. Houghton finished second in the West PAC, and Kingsford was runner-up in the GNC – and Houghton defeated the Flivvers 40-36 on Feb. 19.
Cadillac
1. Big Rapids (17-4), 2. Fremont (19-3), 3. Cadillac (13-8), 4. Ludington (14-8), 5. Reed City (12-10), 6. Newaygo (12-9).
This rare bracket with six teams with winning records seems full of possibilities. Big Rapids, Newaygo and Reed City were the top three teams in the Central State Activities Association Red, respectively, while Ludington and Fremont shared the West Michigan Conference Lakes title and Cadillac is coming off a third-place finish in the Big North Conference. Cadillac defeated Ludington 44-31 on Feb. 9, which will be notable if both reach Friday. But any number of scenarios could play out, including a rematch of those Lakes champs after Fremont won their first meeting by 12 but Ludington won the second by a point in double overtime.
Grand Rapids Kenowa Hills
1. Grand Rapids Covenant Christian (21-0), 2. Grand Rapids West Catholic (16-5), 3. Allendale (10-12), 4. Grand Rapids Kenowa Hills (9-13), 5. Wyoming Lee (1-17).
The intrigue of this bracket centers on the expected championship matchup between the top seeds. Covenant Christian has nine wins over opponents with at least 14 this winter, including league champs Cedar Springs, Big Rapids, Kalamazoo Christian, Shelby and Holland Christian. West Catholic – the Division 2 runner-up last year – finished second in the Ottawa-Kent Conference Gold to undefeated South Christian but has its share of wins over league champs as well, downing Parma Western, Saginaw Heritage, Tecumseh, Frankenmuth and Grand Rapids Catholic Central.
DIVISION 3
Kalamazoo Hackett Catholic Prep
1. Kalamazoo Christian (16-4), 2. Kalamazoo Hackett Catholic Prep (18-4), 3. Lawton (13-8), 4. Comstock (1-21).
Kalamazoo Christian finished one game ahead of Hackett in winning the Southwestern Athletic Conference Valley title, claiming their Jan. 23 meeting by 32 points – but losing the rematch by one last Tuesday. Still, that was the Comets’ first defeat in over a month, breaking an eight-game winning streak. Similarly, that win was part of an 11-game winning streak for the Irish that ended with a loss to Hopkins on Friday. Lawton is another intriguing contender; it’s won seven of its last eight games, with defeats by only one to K-Christian in the midst and two to Hackett before starting the run.
Napoleon
1. Jackson Lumen Christi (18-3), 2. Grass Lake (20-2), 3. Hanover-Horton (17-5), 4. Springport (8-12), 5. Napoleon (5-17), 6. East Jackson (4-18).
The Titans capped their regular season with a 58-56 win over Beaverton (19-3) on Saturday and just as impressively lost to Rockford by only five last Tuesday. They reached the Quarterfinals last season having defeated Grass Lake in the District Final. Grass Lake fell in its regular-season finale to another Division 1 power, Wayne Memorial, by six points, but that was the Warriors’ first defeat since losing to Rockford on Dec. 13. Grass Lake had a big win over Hanover-Horton to start January, but the Comets’ only other losses were two apiece to Brooklyn Columbia Central (18-4) and Division 2 Michigan Center (19-3).
Ovid-Elsie
1. Pewamo-Westphalia (20-2), 2. Hemlock (20-2), 3. Ovid-Elsie (15-6), 4. Ithaca (12-10), 5. St. Louis (11-11), 6. Chesaning (10-11).
A pair of league champions with significant tournament experience anchor both sides of this bracket, with the Central Michigan Athletic Conference’s Pirates having lost to only Division 1 Saginaw Heritage (16-6) and Division 2 Flint Powers Catholic (19-3), and the Tri-Valley Conference Blue’s Huskies fell only to Division 1 Midland Dow (14-8) and Division 2 Freeland (16-6). P-W and Hemlock both won District titles last season. Ovid-Elsie has won at least 18 games the last four seasons and will get to that number again with a championship this week. The Marauders played a good handful of Division 1 and 2 teams as well this season and finished second in the Mid-Michigan Activities Conference.
DIVISION 4
Hale
1. Mio (18-4), 2. Au Gres-Sims (19-3), 3. Hale (14-5), 4. Fairview (4-12), 5. Whittemore-Prescott (2-12).
The expected District Final in this bracket would be the third matchup this season between Au Gres-Sims and Mio, which played each other twice over four days in mid-February with Au Gres winning the first by seven and Mio the rematch by four. That led to their sharing the North Star League Little Dipper title. Placing third was Hale, which is a combined 31-11 over the last two seasons and took Au Gres to overtime in their first meeting this winter.
Ishpeming
1. Ishpeming (18-3), 2. Munising (16-5), 3. Cooks Big Bay de Noc (18-2), 4. Eben Junction Superior Central (5-12), 5. Rapid River (5-16).
The Hematites are only two seasons removed from winning the Division 4 title, and they’ve looked to be in similar form most of this season with losses to only Division 2 Negaunee (21-1), Gladstone (18-4) and Houghton (16-6). Ishpeming also defeat Munising significantly in their lone regular-season matchup Feb. 16, but the Mustangs have won three straight District titles and know what it takes as well at this time of year. Big Bay de Noc is intriguing and takes on Munising on Wednesday. The Black Bears won the Northern Lights League and have totaled at least 16 victories four straight seasons.
Saginaw Michigan Lutheran Seminary
1. Saginaw Michigan Lutheran Seminary (16-6), 2. St. Charles (17-5), 3. Bay City All Saints (14-7), 4. Merrill (15-7), 5. Saginaw Arts & Sciences (10-10), 6. Saginaw Nouvel Catholic Central (4-18).
St. Charles and Merrill finished first and second, respectively, in the Mid-State Activities Conference East, while MLS was runner-up to Hemlock in the TVC Blue and All Saints won the Big Thumb Conference Red title. MLS opened this season with a 53-44 win over St. Charles, defeated All Saints 60-51 on Jan. 29 and Merrill 54-34 a week later, and may have to see two of those again with Merrill playing SASA tonight on their side of the bracket and St. Charles and All Saints possible Friday opponents.
