this is a tough one. I need to check the tape again but here are some thoughts.
1) Asians do not perform well in UFC. However, KZ has lost only to really top guys in the last few of his fights.
2) KZ has not been active due to military service or something (his last fight was far too short for him to gain any real experience)
3) Yair isn't too bad since he lost to top guys like Edgar.
*I dunno, I think UFC decided to pull the plug on the Edgar vs KZ because the betting pool was too lopsided in favor of Edgar. I am so pissed... Ma free money!!!
Anyways, going back to the topic, slim chance for KZ.
prediction: Yair TKO
