Maybe he just needs a change of scenery. I wish him luck.
A couple lessons ... coaching matters. On the offensive side of the ball, there was severe coaching malpractice by the previous regime/staffs. There is no question that affected GRob, because everybody else got worse when they came here. But if probably affected him more, as his confidence was sh!t.
Another lesson, in conjunction with the above ... if you are going to emphasize athleticism, you'd BETTER have a staff that can coach the guy up into a good football player. During Fisher's tenure, at least with the higher picks, he seemed to emphasize athleticism over all else. That worked ok on defense, when you had a good coaching staff that could turn these guys into decent football players. But on offense, emphasizing athleticism over proven ability has gotten us players like GRob and Brian Quick, great athletes who never developed into the players they had the potential to be, in no small part because the offensive coaching staff was at a black-hole level of suckness.
