Video of Mayweather Acting Like an a**!!!!...This is why I hope Hatton KO's HIM

[Violent Demise]

The money is dished out long before PPV and any merchandising money is accounted for.

This statement is so shockingly stupid that I will ignore your future posts unless you retract it.

Fighters get a cut for every PPV buy. So it's impossible for a fighter to know his total earning before hand. I'm thinking Mick phrased it wrong

Right.
A fighter is told he will earn 'X' amount + PPV & merchandising (depending on how it's been worked out).

Right. So, does it benefit a fighter (economically) to actively engage in the promotion to increase the PPV sales? To be controversial? To be loud and obnoxious and to play up a "bad guy" persona if it will generate more PPV sales?

Can a guy have control over his own income by doing that?

Yes
