There's simply too much evidence for people to blind themselves much longer. At one point, Doug Free was a pretty good offensive tackle, at another point, he was an above average tackle, we've now reached the point where he's below average and the team needs to do something.
They obviously can't cut him at this point, but they need to make adjustments for the playoffs before he does cost them something big, and they need to have a plan to have a replacement out there for 2017.
This line and this team are too good to have it all ruined by one guy.
