I believe that Sultan is next for Briggs but..if there was a unification bout it would be Klitschko and Valuev ontop unless Briggs were to lose a lot of weight.

My logic is this........Wlad wins because with the exception of defense, Wlad is an all around better fighter than Oleg or any one else out there for that matter. He is truly a dominant fighter and the best since Holyfield was in his prime.

As for Valuev Briggs..
If we were talking the Briggs that hopped in the ring with Lewis a few years back, then I would probably pick Briggs...but we're not so...
Briggs had a hard time holding his hands up for Sergei who is 6'4. He will aso lose something throwing up as infrequently as he does...imagine him trying to throw punches at the 7'3 trajectory. Plus his punch output just isn't enough.

I don't believe that both of these will happen though, maybe one but not both. There is too much money to be made with the belts the way they are.
