I'm glad we have Allen and am optimistic he can develop, but I wouldn't say he "accomplished" anything so cut and dry that opinions can't reasonably vary.
The expectations for him are crazy high this season. I'm guilty of feeding that at times, myself. But my point is that the jury is still very much out and one could have watched all the snaps last season and have real concerns. Not "he's awful" concerns, but he needs to significantly alter portions of his game to be what we want him to be. I choose to believe he'll get there.
