You know Hornfinger, it used to be that heavyweight title holders would just wait until their mandatory came up to defend their title...The Klitschko's are very active champions...of course Sam Peter is the mandatory now, but Wlad is having a difficult time finding an opponent that will actually fight him. Vitali just doesn't have much time to fuck about with Valuev and Don King haggling over contracts....Briggs took the money and I'm fairly certain Shannon could still beat Valuev so IMO he might not be a better fight but he's a more risky fight.
