INDIANA HIGH SCHOOL FOOTBALL HISTORY

CHAPTER ONE: MIKE GILLIN

47 YEARS. 373 WINS. A LIFETIME ON THE INDIANA SIDELINES.

By Uncle Judd | The Hoosier Gridiron Critic

Indiana high school football changed.

The offenses changed. The rules changed. The classifications changed. The facilities changed. Generations of players came and went.

Mike Gillin just kept coaching.

For 47 seasons as a head football coach in Indiana, Gillin stood on a high school sideline.

Tri-West.

Decatur Central.

Indian Creek.

Mooresville.

Different schools. Different communities. Different generations of kids.

Same result.

Winning football.

When Gillin finally stepped away following the 2025 season, he finished with a career record of 373–157, placing him among the winningest football coaches the state of Indiana has ever produced. At the time of his retirement, the Indianapolis Star listed Gillin third on Indiana's all-time coaching wins list.

But if Uncle Judd is going to tell you the story of Mike Gillin, we're not just going to count wins.

Because 373 doesn't tell the whole story.

Not even close.

BEFORE THE COACH, THERE WAS THE QUARTERBACK

Gillin's football story didn't begin with a headset.

It began behind center.

A 1969 graduate of Decatur Central, Gillin quarterbacked an undefeated team during his senior season and earned All-Mid-State and All-Marion County honors. He later played at Indiana Central and also played semi-professional football before beginning his coaching career.

That's worth remembering.

This wasn't somebody who found football later in life.

Football had been part of Mike Gillin's life nearly from the beginning.

And eventually he moved from running an offense to designing one.

That decision helped shape Indiana high school football for nearly half a century.

THE JOURNEY STARTED AT TRI-WEST

After working as an assistant at Monrovia in 1977 and 1978, Gillin became the head coach at Tri-West in 1979.

And that's where the legend started taking shape.

His final Tri-West team became one of the best teams in school history.

The 1989 Bruins went 13–1 and reached the Class 2A state championship game at the Hoosier Dome.

Think about that.

Thirteen wins.

One loss.

And that one loss came with a state championship sitting on the other sideline.

Tri-West fell to Fort Wayne Bishop Luers 24–22.

Two points.

That's how close Mike Gillin came to leaving Tri-West with a state championship.

There are blowout losses you eventually forget.

Then there are losses that probably stay with a coach forever.

24–22 for a state championship is one of those losses.

But championships aren't the only measurement of a coach.

Sometimes what happens next tells you more.

And Gillin kept winning.

BACK HOME TO DECATUR CENTRAL

In 1990, Gillin returned to the school where he had once been the quarterback.

Decatur Central.

He would remain the Hawks' head coach through 2000.

There's something fitting about that.

The kid who once led Decatur Central on the field eventually returned to lead the entire program.

And Gillin's reputation continued to grow.

He became known not simply as a football coach, but as an innovative offensive coach—somebody willing to evolve rather than coach the game exactly the way it had always been coached.

That matters to Uncle Judd.

Because longevity is impressive.

But longevity while remaining successful is something different.

Football has buried plenty of coaches who refused to change.

Gillin survived era after era because his football changed with it.

THEN CAME INDIAN CREEK

In 2001, Gillin took over at Indian Creek.

And this may be where the story becomes most interesting.

Because he didn't simply win there.

He built consistency.

Gillin produced 16 consecutive winning seasons at Indian Creek before leaving after the 2016 season.

Read that again.

Sixteen straight winning seasons.

High school football doesn't give anybody sixteen straight good years by accident.

Kids graduate.

Quarterbacks graduate.

Great classes come through and leave.

Assistant coaches move on.

Injuries happen.

Enrollment changes.

Competition changes.

And somehow, year after year, the program has to start over.

That's what makes sustained winning so damn hard.

You aren't coaching the same football team for sixteen years.

You're building sixteen different ones.

THE GILLIN NAME BECAME A FOOTBALL FAMILY

And then there was Casey.

Mike's son, Casey Gillin, played quarterback for his father at Indian Creek—and put up numbers that were ridiculous even by today's standards.

Casey finished his high school career with 8,806 passing yards and 104 touchdown passes. During one season he threw 60 touchdown passes, then an Indiana single-season record, and once threw eight touchdowns in a game. Indian Creek went 34–4 during his high school career.

But the Gillin football story didn't stop when Casey graduated.

He became a coach himself.

Casey eventually coached at the University of Indianapolis, served as head coach at Indian Creek, returned to Mooresville as an assistant and offensive coordinator, and later became offensive coordinator and quarterbacks coach at Wabash College.

That's football heritage.

A father teaches his son the game.

The son plays it.

Then the son starts teaching somebody else's kids.

That's how football knowledge gets passed from one generation to another.

AND THEN, AFTER NEARLY FOUR DECADES, GILLIN STARTED AGAIN

Here's the part of Mike Gillin's career I respect perhaps more than anything else.

In 2017, after decades of coaching and hundreds of victories, Gillin took over Mooresville.

He could have coasted.

He could have protected his career record.

He could have decided he'd already accomplished enough.

Instead, he took another job.

And the first season?

3–9.

Now you find out what kind of coach you've got.

A man who had already spent decades winning football games suddenly had three wins.

Did he decide the game had passed him by?

No.

He built another program.

Mooresville followed that first season with six consecutive winning seasons. Under Gillin, the Pioneers eventually captured four sectional championships, a regional championship and a Mid-State Conference championship, and they reached the semi-state round in 2020. Gillin finished his nine seasons at Mooresville 68–40.

That's not hanging around.

That's coaching.

FORTY-SEVEN YEARS

Think about 47 years for a minute.

A player who suited up for Gillin during his first season at Tri-West in 1979 could have become a grandfather before Gillin coached his final game.

That's how long we're talking about.

1979 to 2025.

Reagan wasn't president yet when Gillin became a head coach.

There was no internet.

No Hudl.

No MaxPreps.

No social media.

No seven-on-seven circuit like we know today.

Coaches exchanged film instead of uploading it.

Kids weren't making highlight reels on their phones.

And Mike Gillin was coaching football.

Then all of those things arrived.

And Mike Gillin was still coaching football.

That's remarkable.

THE NUMBERS ARE BIG

By the time Gillin retired after the 2025 season:

373 career victories.

157 losses.

47 seasons as a head coach.

Four different Indiana high school programs.

A state championship appearance.

Championships at the conference, sectional and regional levels.

And an induction into the Indiana Football Hall of Fame in 2014.

Those numbers put him in rare company.

But I've always believed statistics tell you what happened.

They don't always tell you what it meant.

WHAT MIKE GILLIN'S CAREER ACTUALLY MEANS

Here's what stands out to Uncle Judd.

Mike Gillin didn't build one winner.

He kept doing it.

Tri-West won.

Decatur Central won.

Indian Creek won.

Mooresville won.

Different enrollment.

Different players.

Different communities.

Different decades.

Same coach.

That's the separator.

There are coaches who stumble into one great class.

There are coaches who inherit talent.

There are coaches who catch lightning in a bottle for three or four years.

You don't catch lightning in a bottle for 47 seasons.

Eventually the excuses disappear and the common denominator becomes obvious.

The coach knows what the hell he's doing.

AND IT WASN'T JUST ABOUT FOOTBALL

When Gillin retired, Mooresville athletic director Matthew Bosworth said Gillin's influence reached beyond wins and losses, describing a coach who helped shape generations of players into better people.

I think that's probably the most important line attached to his career.

Because here's something we sometimes forget when we're arguing about scores on Friday night.

Most of these kids aren't going to play professional football.

Most won't play major college football.

Some won't play another snap after high school.

Eventually the helmet comes off.

The pads go into a box.

And life starts.

The real test of a high school football coach isn't simply whether his players know how to run power, defend the option or recognize Cover 2.

It's whether something he taught them is still useful twenty years later when they're husbands, fathers, employees, bosses and members of their communities.

Do that for 47 years and your impact can't possibly be measured by a win-loss column.

UNCLE JUDD'S VERDICT

I've spent plenty of time talking about what's wrong with high school football programs.

Poor leadership.

Politics.

Bad feeder systems.

Programs without direction.

Coaches who aren't developing kids.

Adults who make youth sports about themselves.

You know Uncle Judd isn't afraid to criticize any of it.

But if I'm going to criticize what's wrong with Indiana football, then I'm damn sure going to recognize somebody who spent nearly half a century doing a whole lot right.

Mike Gillin deserves that recognition.

373 wins don't happen by accident.

Forty-seven seasons don't happen because somebody got lucky.

You survive that long because you love the game.

You win that long because you understand the game.

And you leave that kind of footprint because somewhere along the way, football became about more than football.

Mike Gillin coached generations of Indiana kids.

He coached fathers.

Then he coached their sons.

He built programs.

He developed quarterbacks.

He won championships.

He experienced the heartbreak of coming within two points of a state title.

And after nearly five decades of doing it, he finally walked away from the sideline as one of the winningest coaches Indiana high school football has ever seen.

So when we're talking about Indiana High School Football History, this is exactly where this series ought to begin.

Not with somebody who was famous for a season.

Not with somebody who had one great team.

Start with somebody who devoted almost an entire adult lifetime to Friday nights in Indiana.

MIKE GILLIN

47 YEARS.

373 WINS.

ONE HELL OF A FOOTBALL CAREER.

And now his name belongs exactly where it should.

In Indiana football history.
