Father & Son Seidl Have Much to Discuss, Notes to Compare From Perfect Starts

Matt and Derek Seidl have a lot to talk about these days.

Southeast & BorderThe father and son duo both have highly-ranked, undefeated basketball teams going into the first full week of February, something neither of them saw coming.

“We were hoping for a season like this, but you never think about winning this many in a row,” said Matt Seidl, the father and head coach of the 15-0 Olivet Eagles. “When our season ended last year, we knew our top seven players would all be returning.”

About 50 miles south of Olivet, in Jackson County, Derek Seidl has the Napoleon Pirates off to a 14-0 start. They are sitting on top of the Cascades Conference.

“We have a really talented group right now,” Derek said. “We were 19-3 last year and brought six guys back. Having that experience has been very valuable.”

Olivet is ranked No. 2 in MPR in Division 2 while Napoleon is No. 9 in Division 3. Both are top-10 teams in the latest Associated Press polls as well.

Matt Seidl, 60, graduated from Ypsilanti Lincoln High School in 1981 and went to Eastern Michigan University to become a sportswriter. He didn’t begin teaching until he was in his early 30s, but, by then, was already a veteran coach.

“It was getting difficult because I was always leaving my job to go coach,” he said. “I decided to go and get my teaching degree.”

He wound up in the classroom, which enabled him to dive deeper into coaching. He spent several years coaching at the middle school and high school levels, boys and girls, with stops at places like Pinckney, Ypsilanti, Manchester, Willow Run and Romulus. He was the JV boys basketball coach at Dexter when his son, Derek, made the team as a freshman.

Senior Brayden Wine makes a move toward the basket for the Eagles.By then, Derek already knew he would be on the bench one day as a coach.

“I played for my dad in youth travel stuff, and he was on staff for one year my freshmen year of high school,” Derek said. “He was a varsity coach all growing up. I was always at games. I loved talking to him about the game, the strategy of it, the Xs and Os. Even when I was younger, I thought about coaching someday. Growing up if you would have asked me what my dream job was, it would have been a teacher and coach.”

Derek, 27, graduated from Dexter in 2014. He played four years of college basketball at Lawrence Tech University. After getting his master’s degree and teaching degree, he got his first coaching job as an assistant coach at Chelsea, under Josh Tropea, who also had coached with Matt.

Derek’s first teaching and head coaching job came at Springport in 2019-20. This is his third year at Napoleon.

“It’s been a really good fit here,” Derek said. “Before I started looking into the job, I barely knew anything about Napoleon. It has worked out well.”

Matt is also the athletic director at Olivet. If he would have had his way, Derek would be coaching at Olivet.

“Derek did a really good job at Springport, and we had an opening and he interviewed and was recommended for the job, but before they offered it to him, Napoleon hired him,” Matt said. “He would have been the perfect choice to teach math and coach basketball.”

With Derek no longer in the running, Matt came out of coaching retirement and was named head coach.

“It was going to be a one-year deal, sort of a band-aid to get us to the next year,” he said.

Instead, Matt’s stayed on and put together quite a successful team. The Eagles have gone 47-6 since the start of the 2020-21 season. This year’s team has taken a big step.

Junior Bo Lincoln, a 5-foot-11 junior point guard, leads the team in scoring (17.1 points per game), assists (3.6 per game), steals (3.0 per game) and free throw percentage at 78 percent.

Drew Priddy, a 6-5 senior center, is averaging about eight points and seven rebounds a game, and junior guard Bryce Wine is averaging nine points a game and leads the team in 3-pointers.

“We had quite the youth movement a few years ago,” Matt said. “We go 8-9 deep now and have a lot of experience. Having those young guys play a couple years ago is paying off.

“We are a good team, but we’re not a 70-possessions-a-game type of team. We know who we are.”

Derek Seidl instructs his players. Derek also knows plenty about his dad’s team.

“I definitely keep track of them,” he said. “We talk on the phone on a daily basis – 30 minutes about Napoleon and 30 minutes about Olivet. We bounce things off each other. We run a lot of the same stuff as far as systems. We’re very connected on things.”

Matt and Derek’s teams tried to have a good old-fashioned scrimmage, or exhibition, last year but – with Derek’s team ahead – Matt received two technicals and got kicked out of the game. It’s a fun story for both to tell now.

“That was wild,” Derek said. “It was a cool thing we had going. We were winning so I was enjoying it, but that put a whole different spin on the situation.”

Matt said they probably won’t do that again. Probably.

“My wife said no,” he said. “Derek and I have talked about it, but I don’t know that it would ever happen.”

Derek said one day he’d like to coach with his father.

“I’m very energetic and into it, just like he is,” Derek said. “There are some similarities. I played for him and watched him a lot. I try and pull some of the things he does, being prepared. We get along super well. I don’t know if I could trust him to not get technical fouls.”

He’s kidding, of course.

Napoleon has a core group of four players with a ton of experience.

Devonta Habern is a 5-11 junior who is on the varsity for the third year and runs the show at point guard. Six-foot-5 senior Trent Jester is one of the best big men in the conference. University of Michigan baseball commit Grant Bradley is a three-year varsity starter and outstanding athlete. Holden Vanpoppel is an all-state track athlete who has turned into a pretty good basketball player.

“Grant is super steady and having a great year,” Derek said. “He looks like he’s been in the weight room since he was 5 years old. He can guard anybody. Vanpoppel is an unbelievable run and jump athlete. All four of these guys are averaging in double figures. They are really good athletes who have invested in the program and put the time in.”

“We’ve got a very talented group,” Derek said. “They are a little looser than I am. I tend to be very calculated, kind of analytical and serious. They like to goof around a little bit. They keep me even-keeled. They know when to get serious. It’s good for me to have a group like that.”

Derek said his squad wants to exceed expectations this year.

“We talk about that after every game – don’t be satisfied just because we are undefeated,” Derek said. “There is plenty more to accomplish. Last year we went 18-2 in the regular season and 19-3 overall, but we didn’t win a league or a District. Our guys have bought into that mindset. That’s helped us get to where we are.”

Matt is keeping a close eye on not only his team, but Derek’s as well.

“I probably get more stressed watching his games,” he said. “I’m really proud of what he has been able to do.”

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

December 18, 2024

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).

Keeler, middle, huddles with his team during the 1997 run to Breslin, when the Defenders finished Class D runners-up.“I had to get my priorities right with the Lord,” Keeler said. “I was trying to do too much and lost focus, and it was something that needed to be done. 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.”

Reporter Dean Holzwarth, a longtime member of the West Michigan media, is also the junior varsity head coach and a varsity assistant for the Tri-unity Christian boys basketball program.
