Keeler Approaching Milestone Win Amid Final Season of Legendary Tri-unity Career

WYOMING – Mark Keeler has spent four decades coaching boys basketball at Tri-unity Christian High School.

West MichiganAnd while he has many stories that he shares often, one of his favorites comes from the beginnings of the program.

“We didn't have bleachers in our gym when I first started,” Keeler said. “I would make my boys set several rows of chairs up so people could watch our games. And then they eventually added bleachers that were donated by the church.”

Keeler’s teams have been filling up the bleachers since he took the reins for the 1983-84 season, and he has built the program into one of the most successful in the state.

Now, as he leads his team through the opening month of his 38th and final campaign, Keeler is nearing a rare milestone only achieved by a few. He is expected to soon become the fourth coach in MHSAA history to reach 700 wins.

Tri-unity is 3-1 this winter, making Keeler a combined 697-217 coaching the Defenders. Roy Johnston is the winningest coach in state boys basketball history with 833 victories earned during stints at Yale, Howell and Beaverton before retiring in March. He is followed by longtime River Rouge coach Lofton Greene (728) and Clarkston’s Dan Fife (703).

“It's a statement of longevity with these men,” Keeler said. “All three of them were very successful at the schools they were at and most of them spent a long time at one school, just like I’m doing now. I’ve never coached anywhere but Tri-unity, and that is quite a privilege to have been a part of this school.”

Keeler reached 697 wins with last week’s nonconference victory over Wyoming Kelloggsville and can move closer to the milestone with another Friday night against Grandville Calvin Christian. The Defenders then play East Grand Rapids and Grand Rapids West Catholic, respectively, at the Cornerstone University Holiday Classic at the end of the month.

Keeler, who retired from a 40-year teaching career two years ago, started coaching in 1983-84 when Tri-unity had only an eighth and ninth-grade team. After two seasons of playing subvarsity, the school formed its varsity team for the start of the 1985-86 season, with Keeler at the helm. After three seasons with the varsity, he took a break from coaching (but continued teaching and serving as athletic director).

I look back, and it was something that set me up for the rest of my coaching career.”

Keeler returned for the 1990-91 season and has been at the forefront ever since. He has guided the Defenders to six state championships, including last year’s with a victory over Mount Pleasant Sacred Heart in the Division 4 Final. Tri-unity also has won titles in 1996, 2002, 2006, 2011 and 2022, while finishing as Finals runner-up six times. 

Keeler’s teams also have reached the Semifinals 15 times, won 19 Regional championships, 26 District titles and 22 conference championships. His players have filled Class D and Division 4 all-state teams for years, with surely the best-known 2000 grad Chris Kaman – who went on to play at Central Michigan and 13 seasons in the NBA – and Brandon Voorhees, who led Tri-unity to the 2002 title as a senior, went on to CMU and then Park University in Missouri, and played professionally overseas.

“I’m so glad that I’ve been able to just be here this long,” said Keeler, who was inducted into the Basketball Coaches Association of Michigan Hall of Fame in 2016. “I love Tri-unity. My wife taught there, we met there, and my daughters went all the way through and graduated from there, so it's always been a part of my life. There's been so many quality people that have been there along the way.

“I've been very blessed to have had so many quality players and parents and coaches. It’s amazing when I look back at all those that have been a part of the program.”

Keeler, a man with a strong Christian faith, could’ve gone elsewhere during his career, but believed he had a calling at Tri-unity.

“I've had some opportunities to move on and go to different places, but whenever I prayed about it I always thought that this is where the Lord wanted me and that's always my priority,” Keeler said. “I want to please him first, because as a Christian that's my priority. I just thought this is where he placed me, so I’m going to set roots and do the best I can.”

Tri-unity senior guard Keaton Blanker, one of two returning starters on this year’s team, is excited to see his coach reach such a prestigious milestone.

“It’s the perfect scenario for him with this being his last year and getting to 700 wins,” Blanker said. “He’s going to leave his mark, and it’s well deserved. Being a small Division 4 school, he’s helped to put the program on the map and I remember growing up and watching his teams win state titles. I was waiting for the opportunity to play for him so I could help do the same thing.”

While Keeler is grateful for the unbridled success of the program on the court, creating lasting relationships with his players off the court and helping them grow in their faith has been equally gratifying.

Keeler raises the 2002 Class D championship trophy to the cheers of Tri-unity’s supporters. “I know without a doubt that the Lord has blessed our program.” Keeler said. “There are a lot of great coaches out there that are probably better at Xs and Os than I am, but I think I’m a strong motivator and build good relationships with the players and get to know them.

“I let each player know that I want them to grow in their walk with the Lord, and that's where my priority is. To be an influence toward Christ, not away from Christ.” 

Past Tri-unity standout Brent Voorhees, who has been Keeler’s assistant coach the last several years and will succeed him next season, said Keeler has never changed his approach to the game.

“Coming back to coach with him, the one thing that stands out is he doesn't waver on his principles,” Voorhees said. “A lot has changed in the sport in terms of analytics and how coaches attack things, but he has definitely stayed firm in his approach that it’s defense first and he preaches the team aspect. It’s never about an individual.

“He doesn’t let anything off the court distract him from goals. He's really good at keeping the goal in front of the guys. He keeps them focused on the goal of winning state championships  and also becoming great, young Christian men in the community, which is what he stands for and always comes first.”

The Defenders graduated eight players from last year’s team, but Blanker and senior Joey Mellon are back with several newcomers as they bid to send Keeler out with one more title at Breslin Center.

“I enjoy putting them together and getting them to mesh as a team,” Keeler said. “For me, I have learned that defense wins championships. The old adage that offense wins games, but defense wins championships ... I so believe that with all my heart.”

'Who Will Cheer for the Nimrods?' Peterson IV, Watersmeet Found Fans Worldwide

WATERSMEET — George Peterson IV talks to a lot of people through his job as a police officer in the Green Bay, Wis., area. When some of those folks are headed up north for the weekend, he tells them he’s from the Upper Peninsula.

These are logos for the Made In Michigan series and the Michigan Army National GuardMany are expecting to hear about one of the bigger towns located a couple of hours drive from Green Bay, like Iron Mountain or Escanaba. But they usually know his hometown, too.

“There’s more people than I would have thought know exactly – ‘Oh Watersmeet, the Nimrods,’” Peterson said.

Some surely know the tiny town because it’s not light years away from Green Bay – only about three hours. But Watersmeet’s dot on the map got a little bigger when Peterson was in school two decades ago, thanks to a run of media exposure that all started with an ESPN commercial that wondered: Without sports, who would cheer for the Nimrods?

Peterson and his teammates can look back on a high school sports experience unlike pretty much anyone else’s, which included the popular ESPN commercial, an appearance on “The Tonight Show” with Jay Leno, and an eight-part miniseries and media exposure from print and television outlets throughout the country. All because of their quirky nickname that has come to be an insult but was chosen because the biblical figure Nimrod was a mighty hunter, and hunting is a big deal in the U.P.

That era also coincided with the best basketball Watersmeet has ever seen. The 2004-05 team, with Peterson was a junior, won its only MHSAA Regional championship and only U.P. small-school team of the year award.

“Great memories from that year,” Peterson said.

The first moments he mentions from his time in high school sports as a aren’t of going to Hollywood – although that certainly came up later – or of being on ESPN. He instead recalled the camaraderie with his teammates, the bus rides, and proving people wrong even in elementary school that Watersmeet could be good.

“The Watersmeet Nimrods weren't supposed to be good,” he said. “We weren’t supposed to win elementary tournaments; we were supposed to fall apart.”

They definitely didn’t do that, as one of the smallest high schools in the state enjoyed instead an unforgettable three-year run.

The cameras first showed up when Peterson was a sophomore. ESPN staff came to get footage early that season, during a December 2003 game against rival Bessemer. The cameras didn’t faze the Nimrods, who upset the rival Speedboys that night; Peterson remembers Bessemer putting 100 on them later that season.

No one told the Nimrods when the commercials were going to air. Then one came on one night when Peterson was watching ESPN.

“That was really cool, just little surprises you weren’t expecting,” Peterson said.

Watersmeet was featured in major newspapers, “CBS Sunday Morning” came to town, and Nimrods merchandise flew off the shelves.

They were even on “The Tonight Show.”

“I would say Jay Leno was probably the coolest experience,” Peterson said. “A small-town kid from Watersmeet, all of us that went, getting treated like we were important, something that a lot of people don’t get to experience. They flew us out, we had limos, we had a hotel right down the road – I think it was a Hilton.”

After the national attention died down during their very successful 2004-05 year – which included the run to the Class D Quarterfinals – the cameras were back for Peterson’s senior year. This time it was the Sundance Channel for an eight-part miniseries about life in his team’s small town.

Those cameras were around that entire season. But if something came up along the way – and it did – the team could just ask the filmmakers to go away while they hashed it out privately. Peterson said they didn’t pressure him to do anything, and the staff members were great to he and his teammates, while doing what they could to make them feel comfortable.

The buzz for the miniseries wasn’t quite the same as for the commercials. But Peterson enjoyed going to a screening ahead of its debut in Madison, Wis. And he can look back on scenes with his late grandfather.

“Now I can show my kids when they get older,” he said.

The basketball part of Peterson’s high school days was a pretty big deal as well.

Growing up, Peterson’s dad George Peterson III took him to the Regionals in Marquette each year. Rooting for area teams like Ewen-Trout Creek kept the fire going.

“I’d go back home, I’d shoot hoops and play ball,” Peterson IV said.

As he and his teammates entered in high school, the Nimrods finished well under .500 his freshman year. The next year, they flipped their regular-season record to 14-6, which included the early season upset of rival Bessemer with ESPN’s cameras recording commercial material.

“And then we were kind of like, ‘OK, we got something here,’” Peterson said.

They went to Michigan Tech’s basketball camp the following summer and won pretty much every game, including against the U.P.’s big schools like Marquette and Iron Mountain.

This Ironwood Daily Globe photo from 2007 shows Peterson talking with “Nimrod Nation” director Brett Morgan.The Nimrods also won constantly early in the 2004-05 season – until Baraga gave them another piece of humble pie. But that proved to be a quick bump in the road. They won their District tournament at home and then both Regional games by double figures.

Watersmeet then lost a heartbreaker in overtime in the Quarterfinal against Posen, but it didn’t diminish what they had accomplished.

For Peterson, he got to do it with his dad coaching, his brother Jordan playing with him and the whole community cheering for them. He still remembers the bus ride home and the reception they got going through Bruce Crossing, part of the E-TC school district.

“We got to experience something we never got to experience before,” Peterson said. “That was probably one of, if not my favorite, moments from my junior year.”

He learned a lot of lessons from that time in his life — just from playing sports  but also from playing for his dad and with the kind of spotlight most small-school athletes don’t see.

“Being an athlete and working in law enforcement, a lot of the lessons learned go hand-in-hand with my profession, because you have to be teachable, you have to be coachable and you have to take the losses,” Peterson said. “Obviously in sports, every time you step foot on the court, we didn’t win. There’s some things in life that you don’t get what you want, but you just learn you gotta work harder for it and strive to be better. That helps me in my profession.”

His dad, who recently retired from coaching boys basketball after walking the sideline for more than three decades, taught his son many things like humility, how to be respectful, patience, and how to respond when things don’t work out.

“That doesn’t mean the door’s closed; you just gotta find a whole different way to get what you want,” Peterson IV said. “I remind myself of that every day when I’m at work.”

As for being in the spotlight, he took valuable lessons from that as well.

“It’s helped me learn to take a step back and not get too excited about certain things,” he said. “Like when I’m around a crowd or when I have stuff going on, like board meetings, or we just have a crowd where people could be mad or people could be in support. It’s helped me to learn to take a step back and mentally just prepare, take that deep breath and everything seems to run smooth.”
