Yes, he has more than pouted on the field. Are you kidding me? Thats laughable....And he has talked poorly about Carson in his final season, as well as bashing the ownership basically his whole stay, but you Chad lovers love forgetting that. To answer the rest as I said before....
Take my chances on a 1200 yard / 80 rec guy that has a chance of getting stabbed/shot/suspended/arrested...rather than a wrestling, dancing with the stars, bull riding player that wont have half the stats BM has. Esp when he sees the cameras for Hard Knocks coming in. I'm sure he'll be the model citizen when things start going wrong.
If the FO found a problem with BM fine, but they should have gotten a suitable replacement. Not grasping at straws on another diva WR with half the talent, claiming they want high quality players. What a joke.
