I think Dallas has gone longer without having a player arrested than any other team. Although Jerry Jones gave Pacman, Tank Johnson and TO chances, he also cut all of them. TO never got arrested; he was just a pain in the rear end.
Actually, I don’t even count Tank, because nothing he was arrested of is even a crime in Texas. He was a victim of draconian Illinois gun laws and nothing more. However, I think you are mistaken about the Dallas arrest record. Didn’t Pac Man get arrested for beating up his bodyguard at a strip club shortly after he signed with Dallas?
