With Golden Tate now claiming opposing defenses know the plays the Lions are running, I vote Caldwell. If true, they have reached a level of damage that can only be repaired by wiping the entire coaching staff clean and starting fresh.
I don't think its a big concern. Cruz won't be himself first game back, and won't see much field unless its 3-wide sets. In that case, I think Robey or Graham get him. I can't see him taking snaps away from Randle in two-wide sets.
Won't matter. His self-defense mechanisms will over power his desire for drawing another flag. One good hit when he tries to pick and he will jump out of the way the next time.
I lived in Greensboro for ten years. Its been a couple years since I've been to Coopers but from what I remember its not a bad place to watch. It isn't a very large place and its on a quieter side of town, so you should have no trouble.
