I'm with skel on this one. If Cal beats Kessler, he should look only at the most established available names, he only has a couple fight left so they should be against the likes of Pavlik or Hopkins. If he beats Kess, he will have already held all four belts, if he were to fight Bute, he'd prob have to relinquish one of the others again, which would be picked up by some other up and comer (e.g. Froch or Brahmer), and there would be some (few) guys out there clamouring for him to fight them, it would just be an ongoing cycle. Only the really big fights from now on.
