“There might be somebody available who fits this unique description: New England’s Trent Brown, who actually was discarded by Shanahan and Lynch back in 2018 (after they drafted Mike McGlinchey).
I’m not saying that Brown is close to what he was in his prime with the Raiders and Patriots (a while ago). But he’s still only 30 and might actually fit into a part-time/depth role these days. And because Tampa Bay and Houston are both surprising playoff contenders so far, I don’t think either Tristan Wirfs or Laremy Tunsil, respectively, are going to come available.
