3. Deontay Wilder (32-0, 32 KOs)
Wilder faces a make or break moment on January 17 as he meets heavy-handed Bermane Stiverne for the WBC belt. We know that “The Bronze Bomber” is big and that he has legitimate one punch power, but his limited level of opposition has revealed little else. A win over Stiverne makes him an instant superstar on the US scene.
