He definitely has the drive to be champion. I've never doubted that. There are other things I might doubt about him but his drive and determination are not amongst them.
He was a starving kid on the streets with barely any food in his belly. He was even lighter than you think, they put rocks in his pockets at a time he had to make weight . The human body gets bigger as you grow older. Look at James n rjjj and Byrd, all middleweight s moving up to heavyweight. That's at least 40 pound gain naturally. I am not a pac nuthugger but he does deserve his propers. We were lucky enough to see him and Floyd in one era, not to mention my favorite fighter who is Miguel cotto who lost to both of them.
