Obviously, he will stay that way, that is the reason he has an undefeated record, that is the reason why he is written in the history of boxing as one of the best. Manny is ready for him if there will be another fight, a rematch. That means that either Manny has a new technique acquired or know how he will be countering Floyd's style.
I hate Floyd Mayweather, but I admit he is not only one of the best but the smartest especially when it comes to choosing opponents. He is also influential and scheming. Boxing can't be won by mere brute force, and career depends on how smart a person or his camp when it comes to accepting matches. This is the reason why Floyd is yet to be defeated. So I do not put high hopes on Manny (even though he is one of my favorites) winning the fight against Floyd unless he knocked him out cold.
Why is it the style of Money is still a big deal. His records and numbers won't lie and that's why he still doesn't have any loss. It's annoying but it's effective with his fighting style. I know it that I'm not the only person that doesn't like Money but we can't deny that his style brought him to fame and riches.
But judges can lie you know. There are fights where Mayweather would have been lost but ended winning because of judges' errors, though we can't blame them since they are only human plus age make them see the other way around sometimes.
With regards to Manny - Conor fight, it is sad that Conor is not one on that three possible matches against Manny.
