My opinion is that manny recently has been easy to find with the lead right hand and coupled with the fact that mayweather is a sharpshooter, i believe he won't be able to take them all night, even though he doesn't have said power, the accumulation will ne too much. I also believe manny will not go into survival mode like other opponents have done. In summary his aggression will be his downfall.
That can be countered with this. If Manny doesn't feel threatened with the power example Algerie, he will open up and become aggressive. That is why I think in my own personal opinion Mayweather is leaning towards strength training. Yes I have no doubt mayweather's right will be there but it won't be enough to stop Manny as in a TKO or KO. This is a 12 round fight because mayweather has an underrated chin also. I'm just trying to be logical and unbiased.
Easy pick's for almost all the fight's I'm tempted to pick all stoppages but law of average says that won't happen. Even still Garcia early/mid KO Matthysse UD in a war Klitchsko mid TKO Mayweather late TKO Canelo mid/late KO
Garcia close UD Matthysse close UD Wladimir Klitschko TKO6 Floyd Mayweather close (maybe controversial) UD Canelo Alvarez (multiple KD's) TKO4
