Actually, I do. I've met him a couple of times. I don't "know him" know him, but I've had the opportunity to speak with him a couple of times for more than just a few minutes.
Nice guy, but those are just minimal first impressions. He's not a pre-madonna like many a NFL star. He makes eye contact with you, and doesn't talk down to you or give off the initial impression that he believes he is better than you. He's friendly enough. He doesn't expect everyone in the room to stop and bow down when he enters.
He comes across like a pretty well rounded guy, but of course, I've only seen that side of him, and have no idea what he's like behind his persona.
However, my impression is that he's a nice enough guy, but his ideals or moral compass were somehow twisted along the way. I don't think he's an inherently evil person, but there is a black and white moral code with him, and if you cross that line, then he will make your life miserable. The problem being that I think his view of right and wrong was somehow twisted along the way.
