I'd have to see how Berto matures first. He still has another 2-4 fights before he steps up to anyone Championship level imo, and that's the way it should be.
Cotto. Berto is coming along but is to young and it would ruin his career to throw him in with Cotto at this stage in his career. If they both keep winning i'd like to see this in 2009
Depending on how Berto looks in his next couple of fights, this could be a great fight...while it lasts! I'll wait too see how Berto develops before I pick a winner.
