Even a lot of the young guns who supposedly can move are going to be working the pocket soon enough. Herbert is going to live or die in the pocket. Burrows will live or die in the pocket. Tua will live or die in the pocket. Wentz' injury seems to have limited him enough that he's going to have to live or die in the pocket. Lawrence, given his weight, had better learn to live or die in the pocket. They might not end up as Bradys/Mannings, and might be more of the Rodgers style, but they're going to need to learn to be somewhere between those two, or they're going to end up with short careers.
I mean, having thought about it over the recent months, I'm becoming less and less impressed with the "mobile" and "running" QBs by the day. So many of them are just an injury away from being RGIII'd, and several others would probably be able to keep playing, but at a greatly diminished level.
