Future Rapists, Drug Dealers, and Murderers Convention 2004
There is a book out called "Out of Bounds" that tracks the criminal record of NBA players. Supposedly almost half the players have criminal records although that might include misdemeanors.
It seems to me that NBA players have received a bum rap as opposed to football players. It's dangerous to generalize, but I don't think NBA players are in the same category for criminal behavior as NFL players. In murder, wife abuse, assault, drugs, violent crimes, it seems like the NFL leads the way.
