Except Bryant has a longer track record of meatheadedness. Stuff that goes back to college. Moss has always been surly and irascible. But he hasn't pulled the stunts that Bryant has.
I mean, he got into a tiff with Bill Parcells and was traded. He got into a fight with Mike Nolan and was also traded. He got into numerous fights with assistants at Pitt. he sued the NFL because he failed a drug test they gave him after he was released from the 49ers (he claimed they shouldn't have tested him because he wasn't an NFL player). He's been arrested for driving 100 pmh in a Lamborghini drunk and then resisting arrest. He had 4 separate run-ins at Pitt. Once for stealing phone access codes, once for fighting with teammates, becoming combative and abusive with campus police (that one, I'm not sure about, since I think it's quite easy to become abusive with campus police--speaking from experience), getting into it with an assistant coach. He was suspended twice by the university.
