Floyd KO Shane. Floyd can't even put down for good a blown up JMM. It will be shocking if Floyd can KO Shane. Shane winning by UD against Floyd is in the realms of possibility.
look at when FMJ knocked JMM down....when JMM got back up floyd didnt even attack him as if he wanted to knock him out, but look at when he caught hatton with that check left hook when hatton got back up floyd attacked and finished the job....
If by KO we include all possibilities (corner stoppage, ref or doctor stoppage), then a Mosley wide decision over Mayweather would be more impressive.
