He should get a lot of credit, but not as much as he would if the fight took place at 147. Beating Cotto at 145 is a monumental accomplishment for a fighter who started where Pac did, but it will be a defeat over a fighter who is not at his best. If it does take place at 145, people will be arguing the merits of the victory for the next 20 years.

One of my main issues (Killer brought this up, I think) is the fact that there is going to be a title on the line; titles should not be able to change hands at catchweights. If it's for the title, it's got to be at 147, otherwise the catchweight is fine (though, like I said above, people will use it as a means by which to debate the merit of the win).

I'd like to see them fight at 147, Pac would still win handily IMO.
