Floyd might have better all around skill than Shane...but Shane definitely has more power. I really feel Floyd was already stretching his frame and power too much at 147...now he is going up to 154. What will happen if Oscar walks through his punches? Because Oscar has a great chin to go along with his big power...his room for error is bit larger than Floyd's. Floyd has to be ultra careful the entire fight...because one punch can potentially end his night...and he doesn't have the power to keep Oscar off of him. Sure he has the speed...but someone of Oscar's skill and intelligence will eventually catch him and force him to go toe to toe. I think Floyd is really banking on the hope that his speed will keep Oscar off of him for the first part of the fight and that Oscar's age will show up at the end of the fight. But if Oscar comes into this fight in great shape and is sharp, which he look like he will, Floyd will have to fight the perfect fight to win.
