The bantering back and forth is almost complete.
On Thursday, Mike and Zachary Zyla will finally coach against each other in a varsity girls basketball game.
It’s a game that both coaches circled months ago when Zachary, 26, got his first head coaching job at Britton Deerfield.
“It’s going to be intense,” Zachary said. “I’m sure he will want to win just as badly as I will. Me and our girls have been talking about the game a lot because it’s a game we think we can win. We want to beat Sand Creek.”
Mike Zyla coaches Sand Creek and is Zachary’s dad. He is a longtime coach in cross country and track and added varsity basketball to his resume three years ago. Zachary, who played at Sand Creek, was hired this past offseason to coach the Patriots.
Both schools are in the Tri-County Conference.
“It’s going to be fun,” Mike said. “We’ve been going back and forth about it for a couple of weeks. We’ll see how it goes.”
Basketball is special in the Zyla household.
Zachary’s other brother, Ryan, coaches at a junior college in Minnesota. His sister, Chelsi, played two years of college basketball after graduating from Sand Creek. Their mom, Kirsten, keeps the scorebook for Mike’s games. She is a special education teacher at Britton Deerfield.
“When basketball season rolls around, that’s all we talk about,” Zachary said.
“I guess it’s a little bit in the bloodlines,” Mike said.
After graduating from Sand Creek in 2018, Zachary served in the Navy. He returned home two years ago and served two seasons as his dad’s assistant.
“I just love the game of basketball,” he said. “I’ve been playing since I was probably 2 years old. It’s the thing I’m passionate about. I watch almost every night. If it’s not a live basketball game, I watch clips of old games. I’m just a junkie for basketball.”
Mike said he misses having his son on his bench.
“I miss having him on staff,” Mike said. “He’s really sharp, picking stuff up on the fly. It was nice having him on the sidelines with me. It’s a good opportunity for him, though.”

Zachary accepted the job in time to have a summer program with BD.
“I’ve always been a big fan of basketball,” he said. “It’s in my blood. I started coaching the Sand Creek hoopsters when I was 16 years old. I knew that’s what I wanted to do. I would say coaching at the varsity level was a goal of mine. It’s always been a dream of mine. I didn’t expect to get a head coaching job so soon. I’d like to get to the next level someday.”
He said he has a few new things for his team to run against his dad.
“He taught me a lot, but our coaching strategies are different,” Zachary said. “I think I’m going to have some things he hasn’t seen yet.”
Sand Creek and BD both lost their season openers Tuesday. Since BD’s game started at 4:30 p.m., Zachary was able to get to Sand Creek to see his dad’s game against Pittsford.
“He was able to scout us,” Mike said.
It’s all in good fun.
“We have a great relationship,” Zachary said. “We bounce ideas off each other all of the time. Even for our first game of the season, we were talking about what we should do, the offenses and defenses. We talk pretty much every day.”
As rare as it is for a father and son to coach against each other, it’s the second time it’s happened in Lenawee County in recent years. Hudson varsity boys basketball coach Jeff Webster coached against his son, Jamison Webster, when Hudson played Tecumseh two seasons ago.
Jamison said it was a great experience, one the Zylas will never forget.
“Coaching and competing against my dad’s teams at Hudson over the last few years has been a great experience,” he said. “We both want to win, being the competitors we are. That being said, the lifelong memories we have made being able to share a sport we both love is what makes it special.”
Zachary said he knows it will be a little different than normal.
“The game’s intensity will be higher than most nights,” he said.
Mike agreed. He doesn’t relish the idea of beating his son, but doesn’t plan on backing down. Since they are both in the TCC, they’ll face off again later this winter.
“We’re both pretty competitive,” he said. “Competitive genes are in the family. I don’t think either one of us will be very happy if we are on the losing side Thursday night.”

Soccer, Hoops Next to Seed Using MPR
August 6, 2019
By Rob Kaminski
MHSAA benchmarks editor
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.
