After what Pac did to him in the first fight i cant blame him. Then again he did fought Margo again so who knows. Could have been weight,Money,Date and place whatever.
cotto probably wants it at 154 and pac would not go higher than 150. and it's a non-sense fight anyway since they have already fought and has a clear winner when both of them are close to their primes.
Another loss would devastate his career momentum at this point.. But thank god anyway, no one needs that rematch anyway.. It would end up more boring than the Barerra rematch.. Cotto has got a good fight coming up,respect for that.
If Pacquaio was willing to go to 154 lbs then the fight would be made. Pacquaio doesn't want to go up any higher than 150 lbs and Cotto wants to have the freedom to weigh 154 lbs or less.
