The Golson debacle is the most short sighted thing Jimbo has done as a coach. He brought in Everette because he thought we could make a run with him. He overestimated Golson's ability and underestimated the difficulty of getting comfortable in his system in a few months, how problematic the OL would be, etc.
Golson seems like a good dude. His biggest problem as a QB is that he literally wilts at the first sign of pressure, and a really good QB has to sometimes stand in the line of fire and still make the play. Golson isn't that kinda player.
