i can't believe that no one has thrown out ken shamrock's name. him and bas have fought a few times in pancrase and i think ken has the most wins, 2-1 on him. i don't think ken is exclusive to UFC either and probably thinks he can beat bas, so i'm surprised he's not trying to redeem himself by jumping into the fight.
5-6 in sig/av bets. I'm the Ross Pointon of Sig bets
