Floyd may be the best to do such. Not only do he adapt to the fighter he's facing, but he changes style during the round. And IMO, throws off more fighters then anything. He can start a round off throwing jabs or 1, 2's. Then a minute in, pocket fight. Then the last minute, counter. His opponents have to have a plan B and C. But most if any, don't know how to go from C to A to B when Floyd adjust.
