On the same day the NFL announced a 10-game suspension for Greg Hardy, Arizona Cardinals GM Steve Keim made a comment that just about sums up how NFL talent evaluators view off-field issues.
Obviously Keim is making a bit of an exaggerated statement, but the point still stands. If you can play quality football, the league will overlook a heck of a lot. The league has had to make some changes in light of Ray Rice's legal issues last year. It took a piss poor performance from the league to get to this point, but at least changes have been made.
