James Toney against either Antonio Tarver or Odlanier Solis. It's unclear what weight a Tarver fight would be at, but I have doubts that Toney could make 200 even if he tried. He's just let himself go for too long.
Devon Alexander versus Marcos Maidana, March 6, on HBO
Humberto Soto versus the winner of Valero-DeMarco. Soto should be ringside to call out the winner, and if Valero wins, Soto-Valero is probably the best fight Bob Arum can make.
Chad Dawson versus Jean Pascal, in June, in Canada. As noted previously, Pascal would need to heal from recent shoulder surgery before he could start training.
Albert Sosnowski versus Audley Harrison. Sosnowski won the European heavyweight title last weekend, and Audley's coming off a Prizefighter victory. I don't even want to think about either of these two getting in there with a Klitschko.
