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.

“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.”

Dock Putting Dad's Coaching Lessons to Work as Middleville TK Continues Climb

November 3, 2025

MIDDLEVILLE – Denny Dock can't pinpoint the exact moment he thought his football-loving son would follow him into coaching, but the signs were there all along.

Mid-MichiganFor starters, there were the countless hours spent tossing a football around the backyard. Or when his young son, Jeff – not even old enough for middle school at the time – eagerly joined other Stevensville Lakeshore coaches watching film on weekends.

Maybe it was all those Friday nights spent trekking along the sideline as a ball boy for Lancers teams. Another clue might have been the Saturday afternoons the two spent together watching college football, or taking in the NFL on Sundays.

When Jeff got older, it may have been how he readily absorbed tips that helped him become a better quarterback in high school and then at Grand Valley State. It could have even been an early, uncanny ability to grasp the importance of fundamentals.

Put it all together, and it seemed inevitable coaching football loomed in Jeff Dock's future.

"That's very fair to say," said Denny Dock, who is 19th on the state's list of all-time winningest football coaches while also the winningest high school softball coach in the country. "The younger years in football were really positive for Jeff, and that doesn't happen all the time. There are negative things that can happen."

While there might have been multiple signs the younger Dock would one day join the coaching ranks, he admits it was far from a done deal. There were thoughts of becoming a biology teacher, a pastor or maybe even an orthopedic surgeon.

But coaching? Even with his father as a classic example of the positive impact a good coach could spread, Dock said it took years for him to eventually land in coaching.

"It dawned on me that there were a lot of all three of those things in being a coach," he said. "Growing up in sports is what I knew, and I ended up developing a passion for it."

That passion is actually the highest it's been in years as his Middleville Thornapple Kellogg football team this past weekend improved to 7-3, continuing the program's first winning season since 2020 and the best fall since the Trojans went 7-3 in 2018. The Trojans defeated Hastings 28-20 in a Division 2 playoff opener, and a win this Friday at Lowell would give Middleville its first District championship since 2001.

Denny Dock coached football at Hartford from 1981-83, Dowagiac from 1984-87, and then Lakeshore from 1988-2013, returning to lead the Lancers for one more season in 2020 and all together totaling a 270-79 career record, 15 league titles and five runner-up MHSAA Finals finishes.

He has kept his hand in football in aiding his son's Trojans program. He's at all the games to add support, critique, advice, strategy, tips on how practices can best be organized and long talks discussing how continual improvement can be furthered.

It's a two-way street as an old football coach who never had a losing season, and is a member of the Michigan High School Football Coaches Association Hall of Fame, can remain invested in the game while his son benefits from three decades worth of experience.

Jeff Dock said his father's real value is his ability to spot from the stands the little things that less experienced coaches may miss.

After playing for his father, Dock said there's no doubt he's transferred the best of what he learned into his own coaching. The older Dock was not only a highly successful football coach, he's compiled a 1,319-345-2 record in softball with eight Finals titles.

 Whether it's about football or the philosophy Dock stresses in his softball program, the advice accepted from his father – who still attends softball clinics for tips on improving the Lakeshore program – is virtually across the board. It begins, however, with how a coach should treat his players.

"I was a manager growing up, and I saw his intensity and a love of his players," Dock said. "He never pushed me in any direction, but he told me about education. He always let me figure it out. One of the coolest things my parents did in raising me was to allow me to figure things out."

As far as the Xs and Os of coaching, Dock said his father prizes an organized practice. In fact, it could even be argued that both Docks enjoy a spirited and productive practice session over the microscope of Friday Night Lights.

"He never had a losing season, and it was ingrained in us just to go back to work and that that work never stops," he said. "He loves practices and being organized. Rule No. 1 with him was to make sure the players are prepared, and that you have to communicate with them. Dad would never belittle us or cuss us out.

"I saw the work he put in, how he'd wake up every Saturday thinking about the game. I saw the nitty gritty of coaching and how it was going to take work."

It was that seemingly endless work, in fact, that Denny Dock made sure his young son understood. Denny had no illusions over the pitfalls of coaching, and the pros and the cons. But before he could teach that to his son the coach, he made sure his son the quarterback understood how athletics worked.

There were challenges as a player and now for his son as a coach.

"He was always a quarterback because I think he liked the ball in his hands," Denny Dock said. "I think he liked the leadership part of the game, understanding the team part, and knowing what he had to do. That always challenged him."

While the challenge of playing is long gone for the younger Dock, the next challenge is building a program which is annually competitive. To do that, Jeff Dock said he accepts what his father knew 30 years ago.

"I'm willing to learn anything from anyone at any time," he said. "I know my dad has always thought about what he can do to become a little better every year. I'm always looking for ways to communicate and do things better. It can always be done better, but how can you get there? How can we do the little things better. That's what I learned."
