This guy is only 31 years old. He is at his peak.
Millions of dollars await him if he does what he loves to do for a few more years. Almost no one quits at their peak. Jim Brown did it after leading the NFL in rushing and Barry Sanders just up and quit. Neither was financially motivated. Brown became a movie star. Sanders said he just lost the desire. I don't see the same thing with AD. He loves to work out. He loves playing football and he's at his best right now. Also, he is the one tackling not the one being smashed. I see 5 more years.
