I don't buy this "Britt was injured last year so that's why he sucked" nonsense. If the only thing that kept him from playing better was injury, why isn't he competing for LG again this year? The simple answer is that he's just not good enough to be an NFL lineman, physical attributes notwithstanding.
It's unfortunate, but I think the best thing for him is to be a depth player. Let him focus his efforts at interior OL off the bench and maybe...MAYBE...he can learn a position where he can thrive as an NFL player. I'm so sick of this effort to find a home for him as a starter when he's obviously not ready.
Hunt might be an answer. He seems to have it right between the ears, but I am not yet convinced that he can handle the physical beating OR a few of the matchups (e.g. Aaron Donald). Patrick Lewis, therefore, is the obvious choice. I don't pretend that he's a world-beater, and I know he has lost more battles against Donald than he's won. Still, he manages the position with competence.
All he does is come in after about half a season and solidify the position time and time again. Why not just insert HIM as the starter (again) and let Britt or Hunt win the job from him? It boggles my mind why we keep sacrificing stability for some experiment that never pans out.
