I would have gone with Brock Lesnar, personally. Or Giant Silva. In fact, Butterbean would be a steallar pick.
i notice thers a lot of common names being thrown out, so there seems to be somewhat of a concensus that bj penn, anderson silva, gsp, randy and fedor whould be mentioned with minor altercations to that list here and there
Georges St. Pierre, Fedor Emelienko, Randy Couture, BJ Penn, Anderson Silva Urihja Faber is a great figher too.
Couture's a lock for my #1. Smart, classy, with great story in his lengthy career and comeback. He's high-profile in the sense that he's a superstar, but not an *******. There's a reason they call him Captain America
I was just bullsh*tting with my picks. I listed all of those guys because they are entertaining personalities. In all honesty - my pick would begin and end with Randy the Natural Captain America Couture.
