Weigh in will give some clues but Cotto-Geale isn't the best example. Cotto was the favorite w/o the catch weight as well which isn't the case (for Broner) here.
It will likely be Al 'Vince McMahon' Haymon's way of explaining why Porter isn't fighting like Porter if he's give Porter money to throw the fight against Broner like he did John Molina.
The thing is Cotto didn't need a catchweight at all. Geale wasn't in his class (neither was Martinez). Here, Broner NEEDS the catchweight because Porter is the better fighter.
No, and please, Cotto under Diaz didn't look good at all. That version of Cotto would've lost to Geale, Martinez, and most likely UD'd Rodriguez. Very much an improved Cotto under Roach. And yeah, this version of Cotto beats any version of Martinez.
