While it's quite possible he could get a brain injury in such an accident, I'm not sure what harm it would do him. Seriously -- you lost a season to a broken leg already. What possesses you to go riding around on a motorcycle, much less being stupid enough to hit a curb going 35?
Everything Kellen Winslow Jr. has done, or said, leads me to believe that he is nothing short of a loud mouth JERK. I especially disliked the way he down played the incident last year with his team mate in Cleveland.
He needs to get himself under control. He expects respect before he has even earned any.
Have some of these young talented players learned nothing from Jay Williams motorcycle accident a couple years ago? Don't do drugs, don't drive drunk, & stay the hell off motorcycles. Are those three little things to hard to give up that will ruin your career.
