Collazo doesn't have the power to hurt Berto. Maybe if he set him up with angles but I don't really see that happening. Luis will give him some trouble early on with his style but once Berto figures it out he'll cruise to victory much like Shane did last year. Too much speed. Even if Berto's punches don't land clean they'll still be flashy. Collazo's a tricky fighter but I don't think he'll be the one to derail Berto.
