When Colts training camp opens, one of the most interesting battles on the defensive front will be on the edge, where Jaylahn Tuimoloau is set to push for a bigger role.
The starting job opposite Laiatu Latu is there to be won, and Tuimoloau will be in the mix with Arden Key for those snaps. That alone makes him a player worth tracking, but the bigger reason is simple: the Colts used a second-round pick on him in the 2025 NFL draft, and Year 2 is where the conversation starts to shift from projection to production.
Tuimoloau’s rookie season was a limited one. He logged just 215 total defensive snaps, according to PFF, so the sample size was small. Still, that first year gave him a foothold, and now he enters camp with a full offseason behind him and more time to settle into Lou Anarumo’s defense.
Defensive line coach Marion Hobby sees the raw tools. "He's a long athlete," said defensive line coach Marion Hobby, via Locked on Colts.
"He's got quickness, but he's got all the natural ability that you want. Just seeing him fine-tune his game is the key to the drills.
He's got to feel comfortable playing, and that's probably the thing from last year, I saw him, he didn't look very comfortable sometimes. But him getting comfortable playing, but long, got good weight."
That comfort level matters, because the Colts need more juice in the pass rush around Latu. As a unit in 2025, Indianapolis finished 30th in ESPN's pass rush win rate metric, a number that underscores how much room there is for improvement.
Key has been a steady presence over the course of his career, but he has mostly operated in a rotational lane and hasn’t delivered the kind of top-end production that changes the picture on its own. Tuimoloau, meanwhile, brings the higher ceiling. Training camp will tell us whether that upside starts turning into real traction.

Colts Just Got Pulled Into Another Quarterback Debate Fans Dread
The Colts have spent enough time trying to sort out their quarterback future without inviting another complicated name into the mix, and that is why the latest speculation feels more like a distraction than a solution. Indianapolis is still weighing what comes next behind Anthony Richardson, while Riley Leonard has at least given the staff a cheaper, cleaner option to consider for the backup job.
J.J. McCarthys appeal is easy to understand on paper because he is still a young former first-round pick, but the fit is where the conversation starts to wobble. Between the injury interruptions, the uneven production and the contract realities, the Colts would be taking on more uncertainty at a position they already know is unsettled, which is exactly the sort of debate this franchise would probably prefer to avoid.

Colts Swing Tackle Battle May Already Have An Undrafted Favorite
The Colts have spent the offseason sorting through a crowded group of undrafted free agents, and the swing tackle competition is one of the more interesting spots to watch. Nolan Rucci and Bayron Matos are among the young linemen the team is optimistic about, and Rucci in particular has drawn attention because of his size, athletic profile and the kind of developmental upside Indianapolis has shown it can extract from unheralded blockers.
Ruccis path is still early, but the buzz around him is real enough that he looks like a name worth tracking as camp approaches. Indianapolis has long been comfortable giving undrafted offensive linemen a chance to earn real roles, and that history gives this battle some added weight as the Colts try to find a swing tackle who can grow into the job quickly.

Shane Steichen Just Gave Colts Fans A Troubling Alec Pierce Update
Alec Pierces offseason has taken a more complicated turn than the Colts probably wanted when the wide receiver went under the knife in late March to address an ankle issue he had been playing through. Shane Steichen said Pierces aim is to be ready for Week 1, which at least gives Indianapolis a target to work toward, but it also leaves the team waiting on a player whose availability was supposed to be clearer by now.
For a Colts offense that could use Pierces vertical presence, the uncertainty matters as much as the injury itself. The surgery was meant to fix something he had managed during the season, and now the real question is how much time it will take before he looks like himself again. Even with the opener circled, there is still no clean answer on when hell be back in full football shape. [Read more 🡒]
