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.

Pilots' Record-Setting Coach Always Eager to Play Role in Helping Students Soar

As if they were fans standing outside an arena’s exit waiting for a famous rock star or professional athlete to come out, Warren De La Salle Collegiate students congregated outside a gate at Grand Ledge High School with bated breath.
Instead of a rock star or athlete, the students had phones up waiting for Thaier Mukhtar, and let him know just how much he was loved.
“Mr. Mukhtar! Mr. Mukhtar!” the students chanted while mobbing him with praise.
Given what he has meant to the school and Michigan high school soccer for nearly four decades, it’s no wonder why the students waited him out.
Mukhtar had just helped lead De La Salle to its seventh Finals championship with a 2-0 win over Hudsonville Unity Christian, and Mukhtar said he was now in elite company with a famous NFL quarterback.
“Everyone was making fun of me because Tom Brady had one more ring than me,” Mukhtar quipped. “Now he doesn’t.”
The Division 2 title was the second straight for De La Salle and finished off a recent stretch full of milestones.
Two seasons ago, Mukhtar became the all-time winningest boys soccer coach in state history when he surpassed Nick Archer of East Lansing by earning his 661st victory.
This year, Mukhtar reached the 600-win mark coaching for De La Salle. That achievement didn’t come with much fanfare, but that was by design and true to form.
“He didn’t celebrate a lot because it’s more about the team,” Pilots senior James Spicuzzi said. “We got him a signed ball, but that was really it. It’s more about the team for him than it is about himself.”
Mukhtar has tried to make that his emphasis since becoming the head coach of De La Salle in 1983 at the age of 23.
The Pilots won their first championship, in Class A, in 1990, and then consecutive titles in 1992 and 1993.
After sharing the 2000 Division 1 title with Bloomfield Hills Brother Rice and then defeating Brother Rice to win the championship in 2005, De La Salle went on a title drought.
Mukhtar actually left his coaching post at De La Salle in 2011 and coached boys and girls soccer at Fraser from 2012-17 before returning as Pilots coach in 2018.
A social studies teacher at De La Salle for 30 years – a job he still holds – Mukhtar admits his coaching style can rub some the wrong way.
“I’m a demanding coach,” he said. “I’m a perfectionist. I call out every little mistake, and I make sure we work on those mistakes. I don’t care if we win 4-1 or 4-0, but are making mistakes. You’re not going to make those mistakes at the end of the year if you don’t want to send your team home.
“I have people – whether it’s parents or players – look at me like, ‘That guy is crazy. They just won the game.’ It ain’t about winning the damn game. It’s about getting here (to the state final) and not making those mistakes. Not committing the foul. Not being out of position. Not communicating in the back. Different things we harp on over and over again.”
Junior Andrew Corder, who led De La Salle with 38 goals this year, said it’s tough love that players have learned to embrace.
“It’s been kind of hard at times, but he just wants the best for us,” he said. “It’s all worth it.”
Mukhtar said he often thinks about retirement, but then points to something his son told him as a reason to keep running it back.
“Every year it’s a battle with me and my administration and, ‘Am I returning? Am I not returning?’ I say to take it year by year,” Mukhtar said. “My CEO at De La Salle made me guarantee that I give him two years (notice) at least. … I give two and then I always say, ‘Why am I doing this?’ My knee is killing me. But when my son says to me, ‘Dad, the fact that you get nervous and the fact you get excited means that you’re not ready (to retire).’ He said it perfectly, and he’s 100 percent right.”
Which is why Mukhtar is likely to continue coaching for the foreseeable future, and why more student celebrations should be in store.
“I’m still teaching at school when I don’t have to, and I’m still coaching when honestly I’ve done everything I’ve needed to do in my life,” Mukhtar said. “I’m like three wins away from 900 career victories coaching boys and girls. I’m still doing all these things because I feel like I can play a role in their life. It’s not just soccer. I want you to be able to believe in yourself and believe that you can accomplish whatever you work hard for. I teach my students the same thing.”
