Oscar would win the fight.

Floyd beat some people but never fought anybody like ODLH, and when you are in the Ring the truth comes to ya REAL fast. He will get confused when he fights a guy that pressures him like Castillo but actually KNOWS how to box and has good defense and Handspeed.

He has MORE then enough power and combination punching to beat floyd and he has JUST enough Speed to do it...

ODLH by K.O.....
