Lol, what? They have had how many players suspended for PEDs from 11-13? They brought in Marshawn AFTER the gun incident in Buffalo. Frank Clark's spat on social media.

This isn't a coincidence.
Marty and Randle were never even suspended when they were Cowboys. They never had legal issues. Irving likes weed, who cares? He's not a murderer. Like I said, JG doesn't like guys who don't fit his mold.
