The source of that article you posted is a good read, in fact McGinn's annual draft columns where he polls execs are always good reads. You may have already posted it but here is that article:
Mcginn on NFL RB's
From that article were this quotes on Mixon. I thought the AFC Exec 4th from the bottom made the most sense.
AFC executive: “How can you in our (large) market? How could you in any market take that guy early or in general? Off the board. Me, personally, I’d have a very hard time living with that.”
NFC executive: “I really think without the incident he’s a top-five pick. He’s probably going to go late first to mid-second. This guy’s just too talented. What he did was terrible. It was three years ago. He got suspended for a year. It’s not like he hasn’t paid a price. Since he did, he’s been fine. It will come down to the owner. I think a lot of owners will be very skeptical doing it. If I was in the 20s I’d take him.”
AFC executive: “He will not be on my board. Impulsive violence against a defenseless woman. I believe in forgiveness, but this is not a matter of forgiveness. It’s natural consequences for an action. I wish him well. ... Once you watch it you become a witness. I don’t need someone else telling me what happened. Maybe I don’t know all the circumstances before and after. A lot of times you’re not sure what really happened. This one, I saw it. He’s had some other times where he’s snapped. Not this heinous. I’ve got to look my wife in the eye. That’s not what I’m about.”
NFC executive: “I wouldn’t feel comfortable. You’re going to have to get up in front of a camera (if Mixon is drafted). If it’s on video now, you have no chance. But they swear by the kid at the school. He probably had too much to drink, but you can’t hit a girl. He won’t be on our board.”
NFC executive: “Off the board. Our guys went and talked to him. They said he was really good. Doesn’t drink, doesn’t smoke. Just made a mistake when he was 18 and is paying for it.”
AFC executive: “To be determined. I’m going to pass on that. Some opinions I get paid for.”
AFC executive: “I am grading the guy as a player. The owner is the one that has to make the decision. There’s other people (football players) out there who have done much worse things. I don’t know what will happen, but I will bet you a team will draft him and he turns out to be a star. I don’t know how you’re going to justify it but if the guy goes out and scores touchdowns people are going to forget about it real quickly.”
NFC executive: “If your owner signs off on it then you go ahead and take him. We’re definitely not going down that road. Whether you take him in the first or the seventh, either you’re making a stand or you’re not. It’s not like some other incidents where drugs or this and that (affect) the value and the round. To me, this is you’re yes or no for him.”
AFC executive: “I did a lot of (expletive) when I was 18 that I’m not proud of but I never knocked out a girl. That’s just such a hot-button issue. I’m hearing too many things. Where there’s smoke, there’s fire. I don’t have the confidence in him to draft him. We can get another back. You may turn down a special guy but the special guy’s got risks. I couldn’t do it.”
AFC executive: “He’s got talent but he’s also been caught on video. I took him off the board.”
