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.”

Tri-Unity Avenges Season-Opening Loss, Earns Retiring Coach Another Finals Win

EAST LANSING — The Wyoming Tri-unity Christian High School boys basketball team was not about to end its season the way it started – with a loss to Fowler.

The Defenders also were not going to let legendary coach Mark Keeler ride off into the sunset after a 38-year career without another Division 4 championship.

On the strength of suffocating defense and two double-digit scoring runs, along with frigid Fowler shooting during the first half, Tri-unity defeated the Eagles 49-32 on Saturday at the Breslin Center to claim its second-straight title and third over the last four years.

Keeler, who announced his retirement earlier this season, departs with his seventh MHSAA Finals championship. Fowler was making its first appearance in the championship since 2002 – when the Eagles also lost to Tri-Unity.

“This is not going to be a good time for me because I’m pretty emotional,” Keeler said. “I’m so stinking proud of them. Was that good defense? I think that was good defense. We played a great team. I thought we didn’t quit.”

The Defenders’ Cody Osbun elevates above three Fowler players to put up a shot. Keaton Blanker led Tri-unity (27-2) with 12 points, followed by Noah Silverton with 11, all in the first half.

“Our biggest emphasis was playing 32 minutes,” Blanker said. “We don’t stop fighting until that final buzzer, and we did that. I’m just so happy for all us players.”

Tri-unity graduated eight seniors from last year’s championship team, with only Blanker and Joey Mellon seeing significant playing time, so another Division 4 title wasn’t necessarily a sure thing, especially after the loss to Fowler on opening night at home.

“I don’t think a lot of people thought that we could do this,” Blanker said. “We just fought. Every day at practice was a straight grind.”

Tri-unity’s defense was smothering all season – holding teams to an average of 39 points per game, the lowest of Keeler’s tenure – and it was downright sterling Saturday.

The first Fowler basket was a 3-pointer by Jacob Halfmann more than five minutes into the contest after Tri-unity scored the game’s first 11 points. That was quickly followed by another 3-pointer by Aaron Simon, but that was all the Eagles could muster as Tri-unity led 11-6 after the first quarter.

Six quick points from Tri-unity – aided by Fowler turnovers – pushed the lead back to 11 less than two minutes into the second quarter. At that point, Fowler had three times as many turnovers (six) as field goals (two).

The lead stretched to 16 halfway through the second quarter, prompting a third Fowler timeout.

A Jacob Halfmann 3-pointer at the 3:15 mark ended another lengthy Fowler scoring drought – and a 13-0 Defenders run – and made the score 24-9. He finished with a team-high 11 points.

The Eagles (25-4) struggled in the first half to find an answer for Silverton, who eclipsed double figures in points before they did.

“Today we just started a little slow. It took a little bit for us to settle in,” an emotional Fowler coach Kam Riley said. “We kept talking about, we got to settle in and be ourselves, and I thought we did that as the game progressed. Against a good team like Tri-unity, you dig a hole, it’s going to be tough to get out of it.”

An Alex Halfmann layup with 2:05 to play in the first half was the first Fowler field goal inside the 3-point arc. Despite a solid finish to the half by Fowler, the Defenders carried a 28-16 lead into the break.

Fowler’s Aaron Simon (30) makes a move into the lane. The Eagles cut the lead to seven late in the third quarter as Tri-unity suddenly appeared mortal.

“They came back at us at the start of the second half, and we knew they would,” Keeler said. “I just thought my guys played great defense. I was more excited about our defense.”

A Clayton Rowlader 3-pointer pushed the lead back to double figures. Fowler pulled within 39-30 with 3:48 to play before Tri-unity closed the game with a 10-2 run boosted by two more 3-pointers by Rowlader. The Defenders finished 4-of-10 from long range after making only one of 23 attempts combined during Regional Final and Quarterfinal victories.

Keeler said this championship was different than the others because it’s his last, and that despite the loss of so many upperclassmen from last year’s team, he had a feeling this team could win it all.

“The competitive part of me, I wanted to win and I knew we could because I’ve watched these guys mature,” Keeler said. “I love defense. It’s the old adage, if you can do offense, you’ll win games, but if you play good defense, you’ll win state championships.”

Keeler finished his career with a 721-218 varsity coaching record, his wins ranking third in MHSAA boys basketball history.
