How dominant does Floyd have to be against Hatton?

[Kel]

Floyd Sinclair.... umm, I mean Floyd Mayweather, is a solid favorite to beat Ricky Hatton, for many reasons.

So, therefore, Floyd doesn't just have to win, he needs to be convincing. Against Oscar, Floyd definitely won, but the fact that it was a competitive fight left some people saying that Floyd wasn't as dominant as he should have been.

So... how dominant does Floyd have to be for it to be considered a successful performance?

Does he need to KO/TKO Hatton? Does he have to win 9 rounds to 3? 10 rounds to 2?

He needs to stop Rick. Rick is the one moving up and taking the bigger risks.
