That's not your cleverest post really is it....

Mayweather hasn't stopped anyone in years either so that fact equals that out, Manny is still knocking people down at least and recently too.
I'm basing this on what a limited skilled fighter (Maidana) was able to do to Floyd for a goo chunk of the first fight.
Now swap Maidana for a southpaw super fast fighter with great footwork and KO power (Pacquiao).

Of course he should go at Floyd like a maniac from the start because Floyd always finds a way to suss people out, re adjust and win on points.

You need to force Floyd to fight at speed and drag him into a situation where he has to fight back- not easy I know but it really is the only way to beat him.

He simply hasn't got the engine to compete like that anymore.

I'd actually be surprised if Floyd won this fight and have Manny as a favourite.
