If I had the money I'd stick a £100 on something that was on 40-1 to happen or something. Or just put another £100 on the Irish, guaranteed £500 back.
Mayweather should not be -500. The dude hasn't ever fought a great fighter until Saturday. If Castillo would have gotten the decision like he should have he wouldn't much of a favorite at all. If anything I would bet on Marquez.
Put down a grand on Mayweather, lose that when Marquez knocks his ass out, then suck a dick for $1200... then you will be up $200.
already stuck my cash on Marquez = i could be wrong but im in for a hell of a win if he kicks floyds ass
