On August 18, 2026, the Buffalo Bills signed DT Greg Gaines and waived DT Tommy Akingbesote. The swap thins one part of the defensive line and thickens another.
Akingbesote was a seventh-round pick by Dallas in 2025, spent time on the Panthers' and Bills' practice squads last season, and re-signed with Buffalo on a reserve/futures deal. He didn't make it through camp. That tells you what the Bills thought of their depth behind the starters.
Gaines is the veteran addition. He doesn't need a roster spot to be proven; he needs to show he can still play a useful snap count. The Bills ran a heavier rotation up front last year, and that's where he fits: as a rotational tackle who absorbs early-down reps and keeps the starters fresh. The move signals the front office wasn't comfortable with what it had behind the top two tackles. It's a low-cost insurance policy, not a scheme change.
The immediate competition is for the third and fourth spots in the interior rotation. Gaines gets first crack, but nothing is guaranteed. Training camp will sort out who earns the snaps when the games count.
Buffalo still has time to adjust before the regular season. If Gaines looks like he's lost a step, the Bills can cut him with minimal damage. If he holds up, they've added a reliable body to a group that needed one. For now, it's a solid, unspectacular roster move that answers a question before it became a problem.
