It's good if you're 100% sure on a floyd win. Bet your house down. Just like those betting barrera against pacquiao.
Or.....DLH or Cotto. There's a reason they call it "Gambling".....there's always a risk associated with whatever it is you are choosing to gamble on. This fight is as close as it gets so the outcome is NOT guaranteed one way or the other. Anything can happen and these two are very evenly matched!
