GL bro
i agree with your sentiments. Pacquiao has shown the ability to move up in weight class, but how much is too much?
if Cotto executes his "plan" as you laid out, he should be OK, but like you said easier said than done as Pacquiao has the speed and endurance to dance around the ring yet he's so accurate he could wear out Cotto?
its setting up to be a good fight BOL!
