I dont know, I have the feeling Ali wouldnt get dragged onto a battle or close scrap with a shorter stronger guy, he would be moving around flustering a forward only fighter who was out to kill him. Rocky also wouldnt be able to land those illegal wrist shots of his if Ali didnt lean down to him and kept his distance with controlling jabs better footwork and a greater reach. I think he would be dumb to lose it or having an ego moment and get dragged into war: Having the grater skills but getting ego'd out and fighting off the ropes to someone with a lower center of gravity and more power in close is an obvious no no,but you never know really.
