To be honest the WBC belt is going to be tied up so McCline/Peter/Maskaev are out of the picture along with probably McCall. I doubt if Ibragimov or Holyfield will be ready after fighting in Oct. and the winner is suppose to face Tony Thompson. Chagaev is fighting Moorer in Dec. so he is out. Being that is a non-title fight I think the best names out there are Valuev, Rahman, Toney, or maybe an up and comer like Kevin Johnson? Another interesting wildcard would be a rematch with Corrie Sanders who is comebacking.
Wlad vs. Iggy/Holyfield at Staples Center in January :good Wlad trains here so he should fight here at least once.
Chagaev or Valuev (...although there'll probably be a rematch between those two if Valuev gets past Liakhovich)
What a sorry list. I say Valuev, only because he's the only listed fighter who's still remotely relevant.
Shannon Briggs would be a possible choice too but wlad doesnt want any part of him because of the high risk/low reward
...and because no network in their right mind would ever buy another Shannon Briggs fight ever again. I wouldn't call it high risk though. Briggs is slow, can't throw more than 10 punches a round and has a mediocre chin. Briggs would be on the end of Wlad's jab all night long until he was KOed in the 6th or 7th or quit on his stool.
