I say mayweather ud. He could hurt Maidana and vice versa, but no way Maidana can win on points. Alexander, Khan and kotelnik showed his he can be outboxed.
Mayweather can drop himbeca use he's accurate but Imo he will box.
I wound like Khan to win because I'm a fan of his boxing, but the way he interviews annoys me so much, and collazo's humbleness madness me half route for the under dog.
I have got Khan to win a ud. Not enough power to hurt Collazo. However Khan and the new weight poses questions. Can he take punches from a relatively weak guy? Remember he Hury Hatton in the 12th. If Khan had learnt a straight right as a first punch, that could be effective.
Broner to get a stoppage for me. He's quite strong in attack vs outmatched guys
