Indiana linebacker Isaiah Jones didn’t come into 2025 spring practice with much fanfare. While All-American Aiden Fisher was locked in at one linebacker spot and sophomore Rolijah Hardy was expected to step into the other starting role, Jones looked like a rotational piece - the kind of guy who’d see time against heavier personnel packages and contribute on special teams.
And honestly, he was fine with that. Jones is the type of teammate who’d rather talk about wins than his own stat line, and it shows in how quickly he shifts the conversation away from himself.
But as the season unfolded, it became clear that Jones wasn’t just filling a role - he was forcing Indiana’s coaching staff to rethink the structure of their defense.
What started as a situational role turned into something much bigger. Defensive coordinator Bryant Haines couldn’t ignore what he was seeing in practice and on tape. Jones, a redshirt junior from London, Ohio, kept flashing - making plays, showing range, and proving he could handle more than just spot duty.
“How can you keep that guy off the field?” Haines said. “He’s so productive when he’s out there.”
And that’s the thing - Jones didn’t just play well in limited snaps. He made himself indispensable. So much so that Haines began tweaking his defensive schemes to get Jones on the field more often, even if it meant stepping outside his usual comfort zone.
Historically, Haines only used three-linebacker looks - like a 4-3 - against heavier offensive personnel. Think two or three tight ends, power run sets.
But Jones’ emergence changed the calculus. Suddenly, Haines was willing to roll with three linebackers against spread sets too - 11 personnel, even 10.
Jones’ versatility gave him that flexibility.
“I can put him to the field. I can put him at the boundary,” Haines said.
“We’ve got some 3-3 stuff we do. Bones is one of the best 11 guys on defense.
Why not play your best 11?”
If you’re wondering about the nickname - “Bones” - that’s Haines’ doing too. A fan of MMA, Haines started calling Isaiah “Bones” after UFC great Jon “Bones” Jones. The name stuck, and now it’s what everyone in the IU program calls him.
Jones didn’t play more than 28 snaps in any of Indiana’s first four games. But then came the Illinois game.
In just 18 snaps, Jones racked up two tackles for loss and a sack. That performance turned heads - and turned the page on his role.
From that point on, his snap count climbed, and so did his production.
By midseason, head coach Curt Cignetti was all-in on Jones.
“Everyone is just so proud of Isaiah Jones,” Cignetti said in October. “He’s a great teammate.
He’s a great leader. He represents everything we talk about - what it takes to be the best you can be.
He is really playing well. I am so happy for him.
He has been a huge playmaker for us.”
And that’s no exaggeration. At one point, Jones was leading the Big Ten in tackles for loss.
He finished the season with 14 TFLs - tied for fourth in the conference - and added seven sacks, good for a tie for ninth. He played 38 or more snaps in each of IU’s final nine games, with his highest snap counts coming in the Hoosiers’ biggest wins - at Iowa, at Oregon, at Penn State, and at home against Ohio State.
Not bad for a guy who didn’t have a defined role coming out of camp. Jones ended up earning third-team All-Big Ten honors, a nod to both his production and his impact.
What made Jones so valuable was more than just his ability to make plays. It was his football IQ and his willingness to learn all three linebacker spots in Haines’ system. That allowed him to step in wherever needed - even filling in for Fisher during stretches of two games - without the defense missing a beat.
“Once you know the defense, you know the rotations, and you know all the spots, it kind of makes it easy,” Jones said. “If I’ve got a rolled out corner outside of me or a safety rolled down inside of me, I know how to box the ball back or spill it. Honestly, learning and playing all three positions has just let me play faster.”
That speed - both mental and physical - has become a cornerstone of Indiana’s defense. And with Fisher eventually moving on, Haines already sees Jones as the next man up in the middle.
“One day, number four’s not going to be out there for the Hoosiers playing mike linebacker,” Haines said. “And the next guy in that line is Bones Jones. I think he is up to that challenge.”
From role player to defensive centerpiece, Isaiah “Bones” Jones has earned every snap, every accolade, and every ounce of trust from his coaches and teammates. And as 2026 approaches, he’s not just on the radar anymore - he’s right in the middle of everything Indiana wants to be on defense.
