If the first fight was something like Holyfield vs Lewis I, Morales vs Pcaquiao II and III, etc. Then yeah, I would also be like "Who would really want to see that fight again?!" But Oscar and Floyd were pretty close, no wonder it was a split and still many boxing experts comment on how the fight could have been Oscar's. There are more fights out there from Floyd that even if he doesn't KO the guy he convincingly shows that he deserved the decision. His fight against Oscar simply doesn't.

I'll say that the guys that have caused more trouble or given more challenge to Floyd so far has been Jose Luis Castillo I (which many boxing experts think Castillo got robbed) and ODLH.

Cotto vs Floyd? That is a fight I wouldn't really want to watch. It would just be another decision for Floyd, maybe even a KO.
