re: Raiders killed Jamarcus

Jamarcus was a number one pick, a football star and he became rich because of it. He was in the limelight because of that good fortune.
He did not handle his success well and he has earned a reputation for his well-documented exploits. That's his, just as fully as the multi million dollar signing bonus.
Nobody with the Raiders or on this site "ruined his character". His character, for better or worse, was on full public display.
