WARREN — There was no hesitation for Andrew Corder about whom he would make the recipient of this thank-you note.
Each Thanksgiving, students at Warren De La Salle Collegiate are asked to write a note to a teacher or coach at the school detailing why they are thankful for them and the positive influences they’ve had on their lives.
Last year, Corder, who is now a senior soccer standout at De La Salle, chose to write a note to longtime teacher and soccer coach Thaier Mukhtar, essentially thanking him for an impactful decision that was made when Corder was a freshman.
Throughout his club soccer days growing up, Corder primarily played as a defender/center back. But when he arrived at De La Salle, Mukhtar had other ideas and put him at forward.
“I think it said, ‘Thank you for everything you’ve done, or like, thank you for putting me at forward,’” Corder said of what was written in the note. “‘I wouldn’t be where I am today if you didn’t do that.’ Something like that.”
That decision certainly changed the course of Corder’s soccer career and the history books for De La Salle’s tradition-rich program.
The Pilots have had a lot of great players, but Corder has achieved statistics unmatched in program history.
Last year, Corder broke the single-season goals record when he netted 38, overtaking the previous set by Brady O’Toole (31) in 1987.
Earlier this year, Corder also surpassed O’Toole (who scored 74 career goals) as the school’s all-time goal-scoring leader, and Corder also became the program’s all-time points leader.
To achieve the latter, Corder surpassed De La Salle legend Brian Maisonneuve, the Mr. Soccer Award winner in 1990 who went on at Indiana to win the Hermann Trophy as the nation’s top college soccer player before an extensive career with the Columbus Crew.
Maisonneuve, who had 104 career points at De La Salle, is currently the men’s soccer head coach at Ohio State and is showing interest in Corder as a college prospect.
“It means a lot, and I’m grateful,” said Corder, who had a goal and three assists in a Division 2 District game Thursday against St. Clair to run his career total to 90 goals, 19 of which have come this year despite constant double and triple teams.
Mukhtar said the big motivation for putting Corder at forward when he was a freshman was De La Salle had been decimated by graduation losses heading into that season, and putting Corder up top gave the team its best chance to win.
Admittedly, Mukhtar is a hard coach to please – and he has made it a point to push Corder equally as hard as everyone else on the roster.
However, it speaks to what Corder’s done that he not only has embraced that type of coaching but has earned such high praise from Mukhtar.
“Andrew is the most explosive and dynamic offensive player I’ve coached in my 43-year career,” Mukhtar said.
There also hasn’t been anything cheap about Corder’s stats. De La Salle always plays a tough schedule including several bigger schools that often are ranked, so he’s not simply feasting on inferior competition.
“We’re fortunate that when you have someone like that, it doesn’t matter who you play, you can always find a way to win the game because of his ability to lift a team offensively,” Mukhtar said.
Corder could also pass as a great historian for the De La Salle program, given his father played there and was part of two Class A championship teams during the 1990s, and Andrew grew up attending camps at the school.
There is plenty of motivation in the coming weeks for Corder to be a part of a third-straight Division 2 championship team at De La Salle. One, it would mean he wins one more Finals title than his father did. Two, De La Salle would become the first Division 1 or Division 2 program to win three straight Finals championships.
“Coach says it all the time and tries to motivate us,” Corder said.

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.
