I highly doubt there will be a rematch because:
1) I don't think the ppv numbers will be too great for this fight and not enough to warrant a rematch.
2) Floyd clearly won the fight and he wouldn't want to send the the wrong message.
3) Floyd isn't getting any younger, I don't think he would want to waste one of his last three fights on Maidana again - much more interesting fights to be made
4) Maidana's too dirty and who knows what he'll try to pull next time in order to get the W.
Nobody was expecting Maidana to put up this kind of spirited effort. A rematch is going to be huge. This was the best possible outcome for Showtime. It buys them time for a another WW fighter to separate themselves from the rest of the pack. For next years May Day event.
So you just admitted Floyd lost to Castillo in their first fight then.
Nope didn't say that, I think you should get your eyes checked. Besides, how does this thread relate to Castillo?
