New Math: Division & Multiplication Problems

July 25, 2017

By Jack Roberts
MHSAA Executive Director 

This is the second part in a series on MHSAA tournament classification, past and present, that will be published over the next two weeks. This series originally ran in this spring's edition of MHSAA benchmarks.

High school tournament classifications went viral before there was social media and most of us knew what “viral” meant.

Much as a virus infects computers today or has created epidemics of disease around the world for centuries, high school tournament classification – once introduced – tends to spread uncontrollably. Once started, it tends to keep expanding and rarely contracts.

While we are still some distance from providing every team a trophy as a result of expanding high school tournament classification across the country, there is criticism nevertheless that we are headed in that direction – a philosophy which is supposed to exist only in local youth sports for our youngest children.

Michigan could be blamed for all this. Michigan is generally accepted as the first state to provide different classifications for season-ending tournaments for different sized schools. It started a century ago. Today, every state has various classifications for its tournaments in most if not all sports. And it is a bit ironic that Michigan – creator of the classification chaos – more than most other states has kept the number of tournament classes or divisions under control.

Yes, there is evidence that tournament classifications have expanded over the years in Michigan, especially with the relatively recent introduction of tournaments in football and the late 1990s’ move from classes to divisions in most MHSAA tournaments. But the MHSAA Representative Council has held true to its word when it expanded the playoffs for football from four classes to eight divisions: this is needed because of unique factors of football, factors that exist in no other sport; and all other sports should be capped at a maximum of four classes or divisions.

Kentucky is the preeminent defender of single-class basketball. All of its 276 high schools compete for the single state championship for each gender. In Indiana, there are still open wounds from its move in 1998 from one to four classes for its 400 schools in basketball.

Multi-class tournaments have tended to increase the number of non-public school champions, which some states are trying to lower through enrollment “multipliers,” and also tend to increase the number of repeat champions, which some states are trying to affect with “success factors” which lift smaller schools into classifications for larger schools if they take home too many trophies.

While there is considerable evidence that state tournaments do as much bad as good for educational athletics, state associations persist in providing postseason tournaments because, on balance, the experiences are supposed to be good for student-athletes. And once we reach that conclusion it is just a small leap to believe that if the tournaments are good for a few, they must be better for more – which leads to creating more and more tournament classifications. One becomes two classes, then three, then four and so forth.

While the argument is that more classifications or divisions provides more students with opportunities to compete and win, it is undeniable that the experience changes as the number of tournament classifications expands. It is not possible for state associations to provide the same level of support when tournament classifications expand to multiple venues playing simultaneously. For example, there is less audio and video broadcast potential at each venue, and less media coverage to each venue. Focus is diluted and fans diminished at each championship.

No one can argue reasonably that today's two-day MHSAA Football Finals of eight championship games has the same pizazz as the one-day, four-games event conducted prior to 1990.

In some states the number of divisions has grown so much that it is difficult to see much difference between the many season-ending state championship games and a regular-season event in the same sport.

It is a balancing act. And Michigan has been studying that balance longer than any other state, and charting a steadier course than most.

Addition by Division

The shift to Divisions for MHSAA Tournament play in numerous sports has added up to a greater number of champions for teams and individuals across the state. Following are the sports currently employing a divisional format, and the procedures for determining enrollment and classification. 

In 23 statewide or Lower Peninsula tournaments, schools which sponsor the sport are currently divided into nearly equal divisions. They are:

  • Baseball - 4 Divisions
  • Boys Bowling - 4 Divisions            
  • Girls Bowling - 4 Divisions
  • Girls Competitive Cheer - 4 Divisions
  • LP Boys Cross Country - 4 Divisions
  • LP Girls Cross Country - 4 Divisions
  • LP Boys Golf - 4 Divisions
  • LP Girls Golf - 4 Divisions
  • Ice Hockey - 3 Divisions
  • Boys Lacrosse - 2 Divisions
  • Girls Lacrosse - 2 Divisions
  • Boys Skiing - 2 Divisions
  • Girls Skiing - 2 Divisions
  • LP Boys Soccer - 4 Divisions LP
  • Girls Soccer - 4 Divisions
  • Girls Softball - 4 Divisions
  • LP Boys Swimming & Diving - 3 Divisions
  • LP Girls Swimming & Diving - 3 Divisions
  • LP Boys Tennis - 4 Divisions
  • LP Girls Tennis - 4 Divisions
  • LP Boys Track & Field - 4 Divisions
  • LP Girls Track & Field - 4 Divisions
  • Wrestling - 4 Divisions

Lists of schools for each division of these 23 tournaments are posted on MHSAA.com approximately April 1. Listings of schools in Upper Peninsula tournaments for their sports are also posted on MHSAA.com. The lists are based on school memberships and sports sponsorships in effect or anticipated for the following school year, as known to the MHSAA office as of a date in early March.

In football, the 256 schools which qualify for MHSAA 11-player playoffs are placed in eight equal divisions annually on Selection Sunday. Beginning in 2017, the 8-player divisions will be determined in a like manner on Selection Sunday as well, with 32 qualifying schools placed in two divisions.

Schools have the option to play in any higher division in one or more sports for a minimum of two years.

The deadlines for "opt-ups" are as follows:

  • Applications for fall sports must be submitted by April 15
  • Applications for winter sports must be submitted by Aug. 15
  • Applications for spring sports must be submitted by Oct. 15

Subsequent to the date of these postings for these tournaments, no school will have its division raised or lowered by schools opening or closing, schools adding or dropping sports, schools exercising the option to play in a higher division, or approval or dissolution of cooperative programs.

When the same sport is conducted for boys and girls in the same season (e.g., track & field and cross country), the gender that has the most sponsoring schools controls the division breaks for both genders.

Genesee's Zinn Setting School, Family Records While Climbing MHSAA All-Time Lists

Special for MHSAA.com

January 7, 2026

Averie Zinn had a front-row seat as her sister Ryleigh re-wrote the Genesee girls basketball record book.

Bay & ThumbAs a middle school student, and then freshman teammate whose parents are the Genesee coaches, Averie saw exactly what it took for Ryleigh to get there.

She also had a pretty good idea of what would be required to overtake her.

“I remember when I was little I was like, ‘Yep, I’m breaking all her records,’” Averie said. “My mom’s sister, she held all of those before. But I just remember when Ryleigh was getting those records, I was like, ‘Well, I’m going to break them.’”

Averie Zinn has broken those records and then some, splashing her name across the MHSAA record book with most of her senior season still to go.

She’s scored a school-record 1,892 points during her career, and with a per-game average this season of 39.8, could surpass 2,000 by the end of next week – making her the 34th girls basketball player in state history to eclipse it.

If that average holds throughout the season, and even if the Wolves play the minimum number of games remaining, Zinn could become just the seventh female in the state to hit 2,500 points.

That, of course, is a projection of where she could be, but she already appears 20 times in the MHSAA record book.

Her 851 points scored a year ago are third highest in a single MHSAA season. Seven of her single-game scoring performances are listed, including five games of 50 or more (she’s added another 53-point performance already this season that is not yet listed). 

Her 21 points in a single quarter are tied for third all-time – she’s since hit 22, which will tie her for second. 

She made 186 free throws a year ago, 10th-most in a single season, and has three games of 15 or more makes from the free-throw line. 

Then there’s the steals: Two seasons in the top 12 all-time with 218 a year ago (third) and 170 as a sophomore (tied for 12th), and five games with 15-plus.

“I just think it’s such a blessing,” Zinn said. “No one really gets that opportunity, it’s such a select few amount of people. I almost don’t even think I’ve processed it. I think it’s really cool, and the fact that it’s happening with my parents coaching me, it’s really cool.”

Zinn elevates for a shot while defended by a pair of Panthers. Zinn, a 5-foot-10 point guard who also takes the opening tip for the Wolves, has scored 199 points through five games this season, going over 30 in four games and over 40 in two of those four. 

She’s recorded 48 steals, as well, going for double digits (11, 12, 16) in each of her first three games. 

“I mean, she’s 100-percent locked in,” said Genesee coach, and Zinn’s dad, Mike Zinn. “She’s been training hard with strength and conditioning, working on her range – a different range. Normally, she shoots from pretty deep, from nearly halfcourt like it’s nothing. But she’s been wanting to work on her mid-range game a little bit.”

As the Zinns have had their successes, so has the Genesee program. This year’s team is off to a 4-1 start, and last year the Wolves won a District title and advanced to a Regional Final in Division 3 for the second time in program history. The first came during the 2022 postseason.

Both of those seasons resulted in 17 wins, which is a school record.

The District title in 2022 was the program’s first since the mid-1990s, when their mom, Megan was playing.

“Mike and I graduated from Genesee High School, and we were the last ones to win a District title,” Megan Zinn said. “We decided to stay in the community, raise our kids in the community and coach here. It’s bigger than basketball. We believe we could work to put Genesee on the map, and that’s exactly what we’ve done. Last year, going to the Sweet 16 was the furthest we’ve ever gone. We lost both times, but just to say that we could get there while coaching both of our daughters is pretty special.”

When Averie Zinn is done breaking records at Genesee, she will continue her basketball career at Wayne State University. 

She committed this past summer to play for the Warriors, a program she’s felt connected to for years. Not only is assistant coach Andy Ayrault a family friend, but Zinn caught the eye of head coach Carrie Lohr while hitting deep 3-pointers as an eighth grader at a team camp.

“I’m really excited,” Zinn said. “I’m getting more and more excited, especially since the new year is here and knowing this is the year that I’m going away and playing there. I know a lot of my teammates already. Wayne State feels like another home to me. That’s what was most important in my decision.”

Genesee won’t be without Zinns, either. While Mike and Megan will continue coaching, there’s also another player coming through, as Averie and Ryleigh's younger sister Maylee Zinn will be a freshman next season.

“I’d say the (age) gap for me and Maylee is like one year too far,” Averie said. “Me and Ryleigh played together, we would go to trainings together. We got super close that year (they were teammates). I always say that to my mom, that I wish I was back a year so I could get that year with Maylee. She’s pretty good.”
