Something else about G Rob strikes me as different from some of the other OL .
He May be a bit of a loner with his peers and I think Jamon Brown is totally the opposite as well as been a better 2way communicator.

I see G.Rob doing his best in media interviews but Brown is actually up there with Saffold as far as being comfortable in front of the Mike and seems to have friends and does well hanging with teammates if Hard Knocks was an indicator.
Bad play and no homies amongst player peers plus coaches backpedaling further and further away from you makes you darn expendable.

G.Robs best minutes and final chance use may come in third and short and goal line plays.
Maybe they should set him up at FB couple times?
