Like Dinucci, Grier should have never played last season. He was simply not ready, mostly due to coming from a spread O and not being ready to play in the pocket. I would imagine CAR was already working on that, so if we can continue his development in that area, we could have some quality on our hands. Dude has a great arm and reads Ds well, just a matter of getting him acclimated.
Grier getting cut was simply a numbers game at CAR. PJ Walker is their backup w/ strong ties to the HC, and their 3rd stringer is a Taysom Hill type, so Grier never had a chance to make the roster.
