1. Tony Thompson (39-5, 26 KOs)
At 43 years of age, the tall, veteran southpaw is no. 1 by pure process of elimination. Two victories over David Price and a win over Odlanier Solis help hide the fact that Thompson has failed miserably in two attempts to dethrone Wladimir Klitschko and that he has come up short in recent challenges against Kubrat Pulev and Carlos Takam.
