If styles make fights how is Pacquiao going to beat Mayweather?

[My 2 Cents]

I'm not hating I think both fighters are great, but I really can't see how Pacquiao (full on attacker) is going to beat Mayweather (full on defense and counter puncher)
Pacquiao had trouble with jmm, (he'd probably beat him now as he has improved) but Mayweather is something else in the countering defense aspect of fighting..
I'm asking you lot, how will Pacquiao beat Mayweather??

The only way Floyd wins this fight is by slugging it out with Pac. That what Morales and JMM did. Floyd can not win by throwing 1-2 counterpunch combo all the time. He has to fight. Judges tend to favor the busier fighter. See Calzaghe vs BHop. If Floyd can not hurt Pac (see Cotto fight) and make him cautious from throwing punches then it's going to be a long night for Floyd.
