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.

With Hodos Again Showing the Way, Pittsford Primed for Another Title Chase

Becky Hodos waited about an hour before she called her husband, Chris.
“I know. I saw it,” he said when he answered the phone.
“I think you should take it,” Becky responded.
The two were discussing a Facebook post in October in which Pittsford announced it was looking for a varsity girls basketball head coach.
“They posted it on the Pittsford Facebook page at 8:30 in the morning,” Hodos said. “I had eight or nine calls by 10 o’clock. Then my wife called.”
Chris Hodos indeed applied, interviewed and got the job as the Pittsford girls basketball coach, returning to a job he thrived before stepping away five years ago. The results have been eerily similar to before.
The Wildcats are 21-0, ranked among the top Division 4 teams in the state and about to start what Hodos hopes is another long tournament run.
“I really didn’t know what to expect from the girls,” Hodos said. “I’ve been away from it. I wasn’t paying very close attention.”
Everyone is paying attention to Pittsford now. The Wildcats have already clinched the Southern Central Athletic Association East championship and are one of just two undefeated teams remaining in Division 4. They are the top seed in next week’s District at Reading.
“There is little doubt having Chris back on the sideline was a good thing,” Pittsford athletic director Mike Burger said. “Our community loves our kids and the effort they put into everything they do. Chris brings energy every day, so I know they are happy with the swagger he brings.
“(Plus) I thought it was good for him,” Burger said. “He just seemed a little withdrawn. Coaching helped bring his fire back.”
Hodos stepped aside after the 2018-19 season. His son was about to play college baseball in northwest Ohio, and he planned on relaxing and watching baseball. He had been coaching football, basketball and baseball at Pittsford.
“No one believed me when I said I was stepping away,” he said.
The Wildcats went to three Class D Finals in a row from 2015-2017 under Hodos, winning championships in 2016 and 2017. If Pittsford defeats Waldron on Thursday, it will be the sixth time in his nine seasons as head coach that the Wildcats have gone unbeaten during the regular season.
Pittsford has had some close calls this season but has found a way to come back even from double-digit deficits in multiple games.
“When you have the best player on the court every night, that helps,” Hodos said.
His best player is Grand Valley State University signee Ava Mallar. She is a four-year starter who is just shy of 1,600 career points, and played significant roles as Pittsford won 18 games each of the last three seasons.
“I honestly was pretty shocked on how well we are doing,” Mallar said. “We lost two seniors, one of which put up a lot of points. I wasn’t expecting this. It’s been awesome. Beating Reading after losing to them twice last year was really good.”
Mallar was a student manager for Pittsford and Hodos years ago.
“I was the manager when he coached my older sister,” she said. “He worked well with our last coach (Aaron Davis). So, when he came, the expectations were the same and practices were sort of the same.”
Hodos also was familiar with Mallar in another way. His day job is as a salesman at Frank Beck Chevrolet in Hillsdale. He sold Mallar a car a couple of years ago.
“He has a good relationship with our whole family,” Mallar said.
Hodos is highly complimentary of his lead scorer.
“She’s the real deal,” he said. “Against Saline (Washtenaw) Christian she had 17 points in the fourth quarter and we came back from 10 points down. She had 27 of our 37 against Reading.”
Mallar said she elevated her game against Washtenaw Christian.
“There’s a point where I know where I have to step up,” she said. “The best part of my game is when I am driving to the basket and making people guard me and creating shots for my teammates. I knew I had to take over if we were going to pull it off.”
Mallar had a triple-double earlier this season and came within two assists of a quadruple-double.
“I honestly thought I had a horrible game, then I found out I had a triple-double. I guess it wasn’t too bad,” she said.
While Hodos has built the team around his star senior, he is also building for the future. Two Wildcats starters are freshmen and two more freshmen come off the bench. He said he is planning to stay at least five years this time around.
“Mike (Burger) asked me if this was just for one year,” he said. “I said, ‘No, I’ll stay five.’ I might stay longer. We’ll see.”
