A big one of the criteria is "character". For instance a college player who gets busted for drugs, or shooting people, or just plain being a rotten person.
IIRC, Dungy has mentioned players that were "DND". Do Not Draft.
And they all had to do with character. Not one had to do with sexual orientation.
BTW, I wonder just how THRILLED the Rams coach is going to be when badgered day in day out about Sam.
Not about how the team is doing. What about SAM?
When Chick Fil A was a soft target, they came hard! When they fought back, homos buckled and ran!
Stand tall Coach Dungy!
