I think Louis could have beaten Ali but don't know if he would have .. with his jab, his own speed and his exceptional two handed power Louis could have been a nightmare for Ali .. a better and more deadly Ken Norton type however when Louis got confused at times he became a plodding follower of a fighter and under those circumstances Ali would decision him .. if Louis went balls to the wall and not catatonic I think he could beat him .. it's a huge if .. it might take a rematch because Louis really didn't make terrific adjustments midfight as much as he was reprogrammed for rematches where he devastated ..
