JG was decent last year. He has certainly regressed. I think Helton had the right idea - have him play within a system of constraints. Now it's all open to him and he isn't able to handle it.
Just one metric of regression - he only had 3 picks all of last year. Now he has 2 in 2 games and could easily have 5. He rarely threw into coverage last year and now it's like he is gung ho and reckless, or simply doesn't see it.
JG may not be very good, but I think he can at least manage in a simpler system. Seems like it is the best adjustment that can be made for him right now. Needs to get out of his head.
Fwiw I think the backups will get PT vs utc. 1 of them would need to absolutely kill it to prove something, otherwise I don't see them benching JG. Everything I've read is maurer and shrout are nowhere near ready. That said some guys are just gamers. Neither showed much in the Spring game, but it's been half a year...who knows? But someone will have to earn their trust, because despite what fans say, it can always be worse - Peterman vs Florida comes to mind. I'd be ecstatic if one of them balls out and turns this ship around. Whatever it takes.
