If he was smart, he would stay away...He has nothing to prove...He will go down as one of the best to never win the title...Although he knows his body like no other human on the planet, he is getting older...And we all know that the older you get, the less predictable your body becomes...It would be a travesty if he made another run at it and came in way off...With the problems he has had with his back and his legs, these are still two body parts that need to be close to perfect to really make a move...
