There's always 1 guy who refuses to fight the best. For a long time it was the WBA title holders post lennox Lewis: Evander Holyfield, John Ruiz, Roy Jones Jr., John Ruiz, James Toney (didn't get to keep the belt), John Ruiz/Nicolai Valuev, Ruslan Chagaev (had belt stolen from him), Nicolai Valuev, and then FINALLY David Haye won it and decided to fight Wladimir after Wladimir had already just thrashed Ruslan Chagaev who was the rightful owner of the belt.

But yeah the WBC belt has fallen into the same circumstance post Vitali. Bermane Stiverne, Deontay Wilder. It's early in Wilder's reign but Molina, Duhaupas, and Szpilka don't really inspire much respect for a guy holding a belt.
