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.

200 Wins Later, Lusk's 'Yes' Still Paying Off as Hanover-Horton Surges

Joe Lusk has had to be talked into coaching a couple of times.
But that hasn’t stopped him from being a winner.
The Hanover-Horton girls basketball coach picked up career victory No. 200 last week when the Comets improved to 12-1 with a victory over Homer. It’s the best start to the season for Hanover-Horton since girls basketball transitioned from a fall sport to winter two decades ago.
“He holds his girls accountable and wants to get the best out of each and every one of them,” said Comets athletic director Chris VanEpps. “We are very lucky to have him here at Hanover-Horton.”
Lusk’s career spans two Cascades Conference schools – his alma mater Michigan Center, and Hanover-Horton for the past five seasons. He was also on the bench at Michigan Center when the Cardinals enjoyed incredible success under coach Scott Furman.
Lusk’s story isn’t the typical one about a high school athlete growing up wanting to be a coach. The Consumers Energy retiree, in fact, never considered coaching basketball until his daughter Courtney came home one day and told him he was coaching her team.
“She was in the fifth grade,” Joe Lusk said. “She told me there was a tournament at Vandercook Lake, she was playing and I was going to coach. I told her no way.”
That no slowly turned into a yes.
After coaching the youth basketball team for several years, Lusk was asked by Furman to join his varsity staff.
“He probably asked me 20 times,” Lusk said. “I kept telling him no. Ten years later, I was still coaching.”
Courtney grew into a varsity player and Lusk became an assistant coach.
“The joke at our house was she was either going to be a good basketball player or she was going to be in therapy,” Lusk said. “She would come home after a tough game and say, ‘Is tonight a therapy night?’”
Not much therapy was needed. The Cardinals went through a remarkable run during which they reached the MHSAA Finals twice and Semifinals another season before Courtney graduated in 2006.
Joe Lusk remained an assistant but, in 2012, Furman died, shocking the Michigan Center community. The ultra-successful coach had won more than 350 games during his career. Lusk took over the job, although he had reservations about becoming head coach.
Over the next nine seasons those reservations were put to rest as the Cardinals won 149 games. In 2018, they went 23-3 and made a run to the Division 3 Semifinals.
Lusk’s last season at Michigan Center was 2020-21. In June 2021, he was hired at Hanover-Horton.
“They found out there was an opening at Hanover and my wife (Cindy) and Courtney put together my resume and sent it in,” Lusk said. “They told me they were doing it. They wouldn’t let me quit (coaching).”
He was hired.
“Having an experienced coach like Coach Lusk is very important for our program,” VanEpps said. “His consistency and effort to make things better, not just for his teams, but for Hanover-Horton in general, give our younger staff someone to model themselves after. As for the girls on his team, he is stern but fair, which is something that can be lost on our younger generations.”
As for his current team being 12-1, Lusk knows the Comets have difficult games coming up. The Comets face Michigan Center (12-2) on Wednesday, Brooklyn Columbia Central (9-2) in a Cascades Conference West game in two weeks and state-ranked Concord in a nonconference matchup. Hanover-Horton also is in a District with powerhouses like Jackson Lumen Christi and Grass Lake. If the Comets win the Cascades West, they will likely face Grass Lake in the conference title game.
“We know the second half of our schedule is loaded,” he said.
Through it all, basketball remains a family sport. Courtney is the Comets’ junior varsity coach. Cindy keeps the scorebook for every game, something she has done for years.
“We are a basketball family,” Lusk said. “If Cindy didn’t do what she does, I wouldn’t be here today. She does a lot of work. For our juniors program, she keeps track of everything, all of the kids, what their shirt sizes are. If I had to do all of that, I wouldn’t be doing it. She loves basketball.”
