I think alot of Cotto's problem wasn't that he fought dumb it was the fact that he was tricked by Pacquiao. The 2nd KD which changed the course of the fight was a result of Pacquiao playing possum and turning Cotto against the ropes. As for Pacquiao's success against Mayweather choosing to run I have a strange feeling he will simply not follow. (I saw hints of this in the Cotto fight). I think that he will be instructed to not lead nor counter but to pressure Mayweather until he is forced to exchange. Hatton had success at catching up to Mayweather but did not possess the handspeed, combinations or in-out angular movement to avoid being clinched. Once Mayweather throws I expect Pacquiao to bite down and simply maul him. If he is able to outwork Mayweather enough times during a round I see him standing still and inviting Mayweather. I know it sounds crazy but I've always wondered why outboxed opponents choose to eat jabs and potshots and follow the outside fighter aimlessly all night long.
