Hardy and Randle are the two that are questionable. We don't know the whole story with Hardy, so who knows. He could be Ray Rice or he could just be a jerk. I think Randle has some real issues. I don't see him as a bad guy, but he might be mentally unstable.
Everything would change if we sign Peterson. At least other players have admitted their mistakes and tried to get better. Peterson is just delusional. He hit a 4 year old with a stick until he was bleeding and they had to get him to a hospital. He has 10+ kids with different mothers and one of them died of physical abuse while still an infant. Do we really think all those other kids are being taken care of? He is a wreck of a human being. Yet he claims the NFL is like modern day slavery... I mean seriously? There is something really wrong with this guy. I have never heard him say he was wrong about anything. It is always someone else's fault. He is not accountable.
I can live with Hardy, Gregory, and Dez. but I don't want anything to do with Peterson. That is where I would draw the line. I can even understand Brent, the dude already spent a year in prison and has to live with guilt. Dez had a rough life, but he is trying to be better. All of these guys (Dez, Gregory, etc) appear to me to be human beings that are not perfect. I doubt AP feels any guilt about anything.
