I have the exact same sentiments when it comes to Richie. He knew he screwed up, paid for it with a year of his career. Whatever it was that straightened him out (I'm assuming medication and psychological help, although I doubt Richie would publically admit it), definitely seemed to have an impact. On the field it's had an impact. The old Richie would have reacted when guys tried to goad him with shots after the whistle. To some degree, it seems he's changed.
Hardy ended up suspended with full pay. Was found guilty in a court of law of serious charges but got off because he paid his victim off. Walked right back into employment in Dallas and maintained his innocence to the point of victim blaming. He hasn't changed because he's not been forced to. He needs to be blacklisted by the NFL for a season at least. See if that has an impact on him. If it doesn't, he's probably way beyond help.
For so many reasons, you're a moron.
