Pretty much every player who has put on the Portagers football jersey over more than six decades of Onekama High School football knows the name Jim Taylor.
And if they didn’t know it before the team’s 52-8 win over Holton on Oct. 10, they do now.
The community of Onekama honored their former coach, celebrated the 50th anniversary of the only undefeated squad in the Portagers’ history and dedicated the district’s new football stadium during the win over Holton – which also helped keep Onekama’s playoff hopes alive this fall.
The Portagers enter this weekend’s regular-season finale at Merrill ranked No. 14 on the 8-Player Division 2 playoff-points list. The top 16 qualify for the postseason, which begins next week.
“We love our history and traditions – all of the generations have just supported each other and built it into what it is today,” said fourth-year coach Justin Sedelmaier. “The former coaches are still involved, mentoring me. … Coach Jim Hunter and Coach Jim Taylor … still coming and seeing and saying hi to the team and stuff every now and then. The ’76 team, a lot of them like Jerry Brown, are always around supporting us.”
Brown, the quarterback of the only Onekama team to finish undefeated, was the primary organizer of the reunion. He was on hand for the celebration, along with Hunter and Taylor, and was even more excited about honoring Taylor than he was about the reunion.
“The motivation behind it for me anyway, personally, was to throw as much light on our coaching staff, and most specifically, the head coach, Coach Taylor, who had such a huge impact on so many lives – mine for sure,” Brown said. “This was all about shining a light on Coach Taylor and his wife, Lora – what a team. She's been right there with him all the way, supporting him.”
Lora Tayler was the school’s cheerleading coach during the first decade of football at Onekama. She was also on hand for the Oct. 10 festivities.
Brown was one of 14 players in attendance to honor the 1976 team, which finished 8-0 and won the Northwest Conference title but did not qualify for the MHSAA Playoffs, which were in only their second year and included only four teams statewide per Class at that time. (Other Onekama teams have since finished perfect for the regular season but lost in the playoffs.)
Taylor started the football program in 1964 and served as head coach until 1988. During his time guiding Onekama, Taylor compiled a 124–58–3 record with only two losing seasons over 22 years. He returned to coaching as an assistant at Onekama from 1997-2008 and was inducted into the Michigan High School Coaches Association Hall of Fame in 2005.
During Taylor’s early years, the Portagers played their home games at nearby Manistee High School while waiting for a home field of their own. The new stadium was built thanks to support of a successful 2024 bond proposal which also provided enhanced security technology, an updated gym, new playground equipment, pickleball courts, team rooms and a modernized press box.
The press box replaced the original built by students in a shop class at Onekama, including the grandfather of the current – and only fourth – coach in the Portagers’ history.
“The press box that just came down was built by the assistant coach, Mr. Foster's shop class, and my grandfather was part of that,” said Sedelmaier, who was the defensive coordinator for four years under John Neph, who with Taylor and Hunter has been the only other head coach Onekama varsity football. “The shop class built the press box and stuff on the first field and just finally now, 60 years later, we're able to make all these field upgrades. It's really been a vision for a long time, and something that I fought for, past players have fought for, the community fought for, and it's a vision that finally came together.”
Sedelmaier was a 2007 graduate of Onekama. Taylor was an assistant coach then. Sedelmaier’s grandfather, Phil Sedelmaier Sr., father Phil Sedelmaier, Jr. and uncle Todd Sedelmaier all played for Onekama during Taylor’s head coaching days.
Justin Sedelmaier has the Portagers primed for another playoff run. They are 6-2, a win tonight should guarantee them a spot in the playoffs and potentially an opportunity to host a game at the new stadium. A loss also won’t necessarily end the season for Onekama, which has reached the 8-Player Division 2 Semifinals the past two seasons. The Portagers’ strength of schedule is expected to boost their playoff chances, no matter the outcome in the regular-season finale.
Bennett Zeller leads the offense. The sophomore quarterback has completed 32 passes for 683 yards and eight touchdowns and picked up 762 yards and 12 touchdowns running the ball. His favorite target is junior Jason Sedelmaier, who has 11 catches for 260 yards and three touchdowns. The next rushing leader behind Bennett is Caleb Porter, also a junior, with five touchdowns while averaging 54 yards per game.
On the other side of the ball, Onekama is led once again by senior Ryan Hrachovina, an all-state defensive linemen last season. He has been credited 103.5 tackles this year – with 22 tackles for a loss and 18 sacks. He blocked a kick and ran it in for a touchdown earlier this fall. He’s also forced a fumble and recovered another.
Jason Sedelmaier also has been a big contributor defensively with 37 tackles, including four for a loss and one sack. He leads the team with 11 pass breakups and has an interception and a fumble recovery, along with a forced fumble.
The Portagers’ only loss last season came in a Division 2 Semifinal to Felch North Dickinson. Coach Sedelmaier is ready to build on the support of Onekama’s former players and coaches as his team prepares to make another run.
“To get to see them all coming back, wearing their replica jerseys and supporting us while we get a look back at some of the history and honoring that history was great for the kids to see,” Sedelmaier said. “That team was the first team to ever go undefeated in the regular season, and they're still the only team that's ever went the entire season total undefeated.”

Byron Brother & Sister Teaming Up Once More

When it was announced Sunday night that Byron was included in the Division 6 playoff bracket, it wasn’t a surprise for the 5-4 Eagles – but it did provide new opportunities.
An opportunity to play another game. An opportunity to avenge a Week 1 defeat against Flint Hamady. An opportunity to stay together for at least one more week as a team.
In the Marvin household, it provided one other unique opportunity: a chance for senior TJ and his younger sister Sarah, a sophomore, to be teammates on the Eagles’ offensive and defensive lines. Sarah Marvin was a captain on the Eagles’ junior varsity team this year, and is among a group of players moving up to the varsity for the postseason.
“That’s awesome to be able to play football with your sister,” TJ Marvin said. “But to play the same positions and not have to go easy, it’s good, because I can still get a good look.”
It’s the second straight year the Marvins have had this opportunity, and in 2017 they actually were able to line up next to each other late in the Eagles’ loss to Ithaca.
When it comes to practice, being on the same field is nothing new as Byron’s varsity and JV teams often practice together. That means brother and sister – who both play defensive end and offensive tackle -- not only share a field, but also get to square off throughout the season.
“It’s fun,” TJ Marvin said. “It’s cool to be up against your sibling. Caliber of player wise, she lines up just like all the other guys, so I’m still getting a good look. It’s not much different.”
The Marvins get to spend plenty of time together athletically, as both are also throwers on the track & field team, along with Sarah’s twin sister, Becky. Sarah and Becky also get to play basketball for their mother, Theresa, who is the Byron girls varsity basketball coach.
“Everyone in my family knows about throwing,” Sarah said. “All of the sports – you can go home and talk about it, and everyone in your family understands.”
Football is also a family thing, but it’s something special TJ and Sarah share. They started playing while she was in first grade and he was in third, and often times found themselves not only as teammates, but also lined up next to each other on the offensive line.
Starting in the male-dominated sport was something Sarah didn’t think twice about.
“I don’t know if it was something that so much drew me to it. It was just that all of my boy cousins always played,” Sarah Marvin said. “I have (two younger cousins, two younger brothers), an older brother and an older cousin, and we would always rough house.”
Theresa Marvin said her daughter has always loved the game -- whether it be watching or playing -- and became a student of it. TJ agreed.
“Sometimes I’ll give her tips and stuff, but she is very athletically smart,” TJ Marvin said. “She knows the game, watches a lot of football and she’s very good at big picture plays and seeing what’s going on. Any sport, really, but especially football where there is so much going on, she really analyzes the game.”
While they started playing at the same time, TJ does have plenty of experience he can pass onto his younger sister. Injuries kept him off the field for the majority of his freshman and sophomore seasons, but the 6-foot-3, 235-pound two-way starter was an all-conference selection as a junior. He also is a varsity captain this season.
Sarah Marvin already has established herself as an all-state athlete, finishing third this spring at the Lower Peninsula Division 3 track & field championships in the discus and shot put. She was also an honorable mention all-state selection in basketball during her freshman year.
Throwing appears to be her future as an athlete, and continuing to play football is something they’re taking year by year.
“All through my freshman year I was dead set on it, that I’m going to play all four years,” Sarah Marvin said. “I think that’s changed a little bit. I had a kind of close call where a kid went to make a tackle and I was behind our running back, and he fell right into my knee. So that’s the main thing, is not getting hurt.”
Worrying about getting injured, however, has nothing to do with Sarah’s gender.
“Sometimes I worry about it, but I don’t worry about her anymore than I would other guys on the field,” TJ Marvin said. “I worry about it a little bit with her coming up on varsity where there are much bigger players and it’s a little more intense, but I know what she can do physicality wise and the kind of athlete she is. I worry about her getting hurt, but I worry about every one of my teammates getting hurt.”
Sarah is simply a member of the team, and she says that’s something that resonates through the program.
“Within my grade level and even the grade older, since I’ve played since the first grade, I think they’re just used to it -- we’re definitely just regular teammates,” she said. “They don’t treat me any different than the other kids; they’re just out there to play football. I’d probably be annoyed if they didn’t hit me as hard as they hit everyone else.”
Despite that, the Marvin siblings realize their situation is unique, and they feel fortunate to be able to experience playing together for at least one more week.
“(Getting on the field together) would be a really cool thing to do,” Sarah Marvin said. “Especially in his senior year.”
