Replace switch young George with old man George in the rumble in the jungle. How does he deal with Ali
Too slow, gets mercilessly clowned. Maybe Foreman goes the distance, not because hes better, but because he barely throws anything, and shells up.
Ali too quick. Instead of strongly attacking Foreman presses using his own jab. However this allows Ali to fight as he planned to fight boxing and moving. It's a 15 round fight so a tough distance for Foreman. However I don't think Ali knocks him out. George struggles to the finish beaten and bloodied. Ali is unmarked. Ali win 15, 12-3 in rounds.
Ali would never had needed to lay on the ropes. He would have stayed in ring center and boxed George`s ears off.
Old George gets cut up and stopped around 12 + in a horrible thing to watch. It's not a shame to say there are some fighters you just can't beat. George can't beat Ali.
