That stoppage you brought up is looking more viable to me, with Pacquiao being smaller as well as persistent, which his persistence is one of his most commendable traits it's also something can get him stopped.
It's intriguing because every southpaw Mayweather faced was made to be more tentative, they eventually got the point and started fighting more uncharacteristic, it's hard to imagine Pacquiao doing the same if a decision lost looks inevitable. Do you see that happening?
Watched the Bradley fights again, Pacquiao is a lesser fighter when he's backed up but one has to do so intelligently, it's too bad Bradley is forced to sell out to do damage/ doesn't possess a straight right hand, although he had quite a bit of success.
Pacquiao doesn't have a jab, it's for blinding purposes and Mayweather's reflexes are too good, it's bad enough that your telegraphing when your gonna shoot your left as it is. Then he doesn't have much of a right hook in the center of the ring, he does when he's got you cornered but nothing Hagler or Whitaker-like IN THE CENTER. It's like, I'm struggling to see how Pacquiao backs Mayweather up
I see Mayweather using the high guard, catching Pacquiao's lefts and returning fire. Right hand lean in, right hand lean in, lean in bend at the waist, lock Manny's right hand...it's scary how other than Morales somewhat...no one has has done this.
The stoppage, not so sure about that one, Mayweather seems too keen on winning by decision, especially with the way he takes the 12th round off nowadays. It can happen but Pacquiao would have to run into something real real ugly.
Whats interesting is that Vanes, who has trained in the wildcard gym is of the opinion that Mayweather stops him, also seems to think it's gonna be like the Hatton fight. Oddly enough (Not sure if I sent you that video) Mayweather sort of alluded to using the same approach as well.
Pacquiao definitely has a lot left but what worries me is that, I'm not worried
I saw that you cited Morales and I agree strongly with that because Morales' lead right hand is the best lead right hand Pacquiao has ever faced. Even in the rematch, Morales who by the 2nd round looked beaten, he managed to summon whatever he had left and was still killing Manny with those lead rights.
