he's got that smile cuz a 500k payday awaits him....
Id be giggling like a little school girl right now if someone waved 500k over myhead.
Peter manfredo, went from a local fighter, to a reality show runner up, taking 3 losses in the show....
500k from the contender,
150k-200k in promotions and appearances.
And now another 500k to get his face pounded.... easily over a mill for a kid that was fighting in local arenas.

I don't see his career going any further after his calzaghe fight, WHEN calzaghe demolishes him, he will either hang it up, OR go back to New england for some local promotional fights.
all in all
over a 1 mill (gross) isnt bad for a kid who was barely clearing 5k a fight before the contender.
