The Indianapolis Colts are gearing up for a significant position battle as they approach the 2026 NFL season, particularly for the defensive end spot opposite Laiatu Latu. ESPN's Ben Solak highlights the competition between Jaylahn Tuimoloau and Arden Key as crucial. Tuimoloau, selected in the second round of the 2025 draft, had a modest rookie season with 17 tackles and six quarterback hits over 13 games. However, he displayed potential towards the end of the season, reminiscent of his standout college performance at Ohio State, where he recorded 12.5 sacks. On the other hand, Arden Key brings eight years of NFL experience, having played for five teams and accumulating 30.5 sacks. While some may view Key as merely a rotational player, his experience could be pivotal in securing the starting role. Predictions suggest that Key may start the season ahead of Tuimoloau, but the latter could emerge as a strong contender for more playing time as he develops. This position battle is one of the most uncertain on the Colts' roster.
