Russell. "Bust" refers to his performance as a football player. Leaf's law issues happened after his career was over and do not effect his performance as a football player.
That, and Leaf had a few decent games. Russell, I think, had ONE good game against Tampa Bay 2 years ago. It also seemed like Leaf was just an jerk, but wanted to play football. Jamarcus didn't want to play football, just wanted to get paid for it.
