It's Only Natural
For any fighter to be confident going into a fight. Although I'm sure Eddie Sanchez knows he is a little in over his head. But he's got some big balls, I'll give him credit for that. I would give Eddie probably about a 1 in 20 chance of winning. Quite simply it can happen, but Mirko is a man on a mission I believe. He wants a title bad, you can tell by his words about Tim Sylvia, and how much he respects each and every champion.
I guarantee he longs for that sort of respect, watch out UFC heavyweight division.
