Good luck with that, they are a very rare breed and get paid an extortionate amount (think they are second highest paid position on average after QB). Nobody is giving up a good or even decent one. Plus Darrisaw is one of the better ones in the league, what do you do when he comes back and have two.
The team isn’t good enough to win a Super Bowl so I don’t see the point in sacrificing the future, for a team with one of the oldest rosters in the league, to get someone in now.
They might be able to find someone better than Quessenberry but the fact he has been in the league for what feels like forever shows how rare decent LT are considering how **** he is
