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.

Undefeated Brandywine Eager to Earn Return Trip to Breslin Center

NILES – Josh Hood recalls receiving multiple texts the Monday following spring break last year.
Those messages came from various players on his Niles Brandywine girls basketball team inquiring about when they could get back into the gym and begin preparing for the 2024-25 season.
After losing a 33-30 heartbreaker to powerhouse Ypsilanti Arbor Prep in the 2024 MHSAA Division 3 Final, the top-ranked and undefeated Bobcats, 26-2 a year ago, are hungry for a return trip to the championship game at Michigan State University's Breslin Center later this month. They open up District play at 5:30 p.m. today against Bridgman on the Bees’ home floor, and will host next week’s Regional.
"Once you get a taste of the type of success we had last year, you can respond to it in one of two ways. You can either take the summer off, have fun and ride out your senior year and be content with what you've done or you can get to back to work right away,” Hood said. “We took a week off and after spring break, there were those texts from our girls asking, ‘Coach, when can we get back into the gym?’ We didn't have to ask who was going to show up each night either when we played our 14 dates and 25-game schedule in the summer. All of the girls were there ready to work.”
Hood graduated his top two players in Ellie Knapp, last year's starting point guard, and post player Kadence Brumitt. The two all-staters led a squad that earned the school's second Semifinals appearance and first Finals berth.
"Last year we had Ellie and Kaydence, who were our top two scorers for four years. The biggest difference this season is that we have eight girls averaging between four and 12 points,” Hood said. “Nobody we play can say they must focus on one certain player. Any one of our girls is capable of scoring. Our ability to spread the ball around and be unselfish have been two of our biggest strengths.”
Despite those two key graduation losses, the Bobcats (22-0) haven't missed a beat even while playing a difficult schedule that's included several games against Division 1 or Division 2 schools.
Brandywine, the two-time repeat Lakeland Conference champ at 8-0, has gotten good performances all season out of its seven seniors, along with a solid group of underclassmen. The Bobcats have taken advantage of their athleticism and quickness to outwork their opponents.
"The great thing about this group is that they aren't just basketball players. The success that we've had here at Brandywine in the last 16 years isn't because they focus just on basketball. Every one of these girls in our program are multi-sport athletes," Hood said.
The experience of playing on the big stage last March has been a big motivator to senior leaders Miley Young and Adeline Gill, along with classmates Adelyn Drotoz, Ireland Prenkert. Lexi Troup, Paige Krisher and Niyah Mason.
Gill, Brandywine's tallest player at 5-foot-9, is the only player averaging double-digit scoring at 12.5 points per game, followed by Young (9.0 ppg.) and Drotoz (8.5 points).
"Adeline is our leading scorer and a four-year starter like most of our seniors. She is a quiet leader who just goes about her business on the court. Her consistency in scoring and rebounding are big assets. Just like Miley, she is a tireless worker," Hood said.
"Miley was another player who received all-state honors last year not for her scoring, but simply because she was the best defender that everyone saw play at Michigan State in the Finals. She brings great tenacity and is fearless on the floor. Her energy on defense keys our man-to-man pressure, and she is the catalyst at the point position. Her work ethic has been exemplary all four years. Every day she is the first one at practice and the last one to leave."
Gill also averages 4.7 rebounds and two steals per contest.
"The experience of playing at Breslin last season was amazing and taught our team a great deal. We know what it takes to get there and how hard we have to work in practice and play in games” said Gill, who next plans to major in biology at Kalamazoo College with her career goal to become a physician's assistant. “We are quick and get lots of steals on defense. This group is hardworking, and we are always getting after it. We study a lot of film on other teams and ourselves, and it really helps us prepare for games. Our team is just really motivated to get back to state,"
Young sports averages of four rebounds, 4.4 assists and 3.1 steals per game.
"Getting to Breslin last year was something we really wanted to do since we were younger. Our team has supported each other very well. We lost two key players from last year, but we have some young talent and returners that have really stepped it up this season," Young said. "Last season we were bigger in the post, but this year we just try to use our quickness to wear other teams out. We might be smaller, but we're going to get the job done with our defense. Most teams don't have the depth that we do, and that allows us to wear our opponents out. We are held to a high standard, and our coaching staff help us to be the best we can be. I've never seen anyone like Coach Hood who watches as much film as he does."
Young said that playing in Knapp's shadow last year was a good learning experience.
"In my opinion Ellie was the best point guard in the state. Going against her in practice really helped me,” Young said. “I had to switch my role up this year knowing I'm not going to get the ball on fastbreaks. I'm comfortable in my new role and getting my teammates the shots."
Drotoz, who will end her Brandywine career as the school's top 3-point shooter, has made 52-of-132 (39 percent) attempts from behind the arc this season.
The Bobcats are a dangerous team with their ability to either drive or swing it back outside for a 3-pointer. Brandywine is 157-of-535 (29.3 percent) on 3-point attempts.
Sophomore guard Mackenna Price (5.5 ppg.) is a big contributor off the bench for the Bobcats. Other standouts seeing heavy minutes are Prenkert, Troup, Krisher, Mason, sophomore Lily Gill and junior post player Karleigh Byrd.
Lily Gill averages seven points, 4.5 rebounds and 3.8 steals, while Byrd is averaging 5.9 points, 3.5 rebounds and 3.1 steals.
Brandywine, which is averaging 58.9 points as a team and giving up just 26.2 per game, owns impressive wins over last year's Division 2 quarterfinalist Vicksburg (45-28), along with Stevensville Lakeshore (45-37), Richland Gull Lake (70-38), Kalamazoo Central (50-34), Kalamazoo Loy Norrix (59-27), Battle Creek Central (56-41) and St. Joseph (51-36).
"When you average what we do offensively and give up only 26 points per game, it says a great deal about our commitment to defense,” Hood said. “With our team it’s always been about defense translating to offense. That's become the culture of our program, and we're going to work real hard at it.”
Brandywine's last three games of the regular season were all against Division 1 schools in Battle Creek Central, Loy Norrix and St. Joseph.
"There's intent behind our schedule. Much of the credit goes to our athletic director (Dave Sidenbender) because we ask him to give us the best schedule that we can possibly have. When you play seven conference champions and 17 of your 22 games against Division 1 or Division 2 opponents, it makes our girls fearless,” Hood said. “Our schedule prepares us well. Losses happen, and you don't lose anything with a little adversity and playing tough competition. If you have a little hiccup, those film sessions are better than if you win by 40 points because you learn from that adversity. Our girls embrace that and they know that iron sharpens iron, and that's why we play the schedule we do. We play the seventh-toughest schedule out of 683 schools in the MPR (Michigan Power Ratings) rankings. When the ball goes up in the air, these girls are ready to play and it’s an honor to coach them."
In outlining the keys for another strong tournament run, Hood identified Brandywine's pressure defense as a key ingredient.
"We've never had a player taller than 5-10 at Brandywine since I've been here,” he said. “We have girls who are only 5-8 or 5-9, so that forces you to make it a 90-foot game and we've done a good job of that all season. Our rotations have been stellar. We feel like we are in charge of what we do on the court with the defensive pressure we apply. We are a very effective team when we can push the ball up the floor and not let our opponents get comfortable in the half-court.”
Young has committed to play college basketball at Lake Michigan College, while Adeline Gill made a recent verbal commitment to play at Kalamazoo College. Troup will play women’s soccer at Trine University and Drotoz plans to continue her softball career at Alma College.
