I seen to recall a 10 or so year span that the vast majority of the Cowboys were criminals of some sort. Personally they need to be held to much higher standards and any and all convicted criminals should be banned from ever playing in the NFL again. Traffic tickets for speeding are one thing but beating your wife/girlfriend, DUI manslaughter, drugs, murder etc... are another thing and have no place in the pros where many are looked at as supposed role models for children.
But what if the NY Giants passed on LT because of his proclivity for criminality? It would have been a nice gesture and speak volumes to the organizations commitment to morality but in the same breath they would have passed on (arguably) the greatest defensive player in history. That's a tough call
