Which is a bigger number than i thought it would be. And being in camp in August is far different thing than making the roster or even the practice squad.
But 3 of the 5 OL on the 2021 team look like they are going to be starters this year:
Gaines @ C for the Cards (he looked excellent v the Raiders)
Ryhan @ LG for the Pack
Alec Anderson @ LG for the Bills
Mafi has made NFL rosters in 2023 and 24...he was another OL from the 2021 team.
