Race has very little to do with anything football. I'm talking on the field, in the locker-room, at practices, and in film study. And the ONLY time I could see race even enter the conversation would be amongst the players themselves. The rest of 'race' talk is outside football with media, fans, talking heads, etc.
Pickens doesn't have an attitude because of his race, he has attitude because he knows he's that good. This offense should prioritize getting him the ball. Keyshawn Johnson wrote a book about it.
