I don't know-

Sam Peter has learned over 2 fights with James Toney he can't always rely on his power. Also with the 2nd Toney fight we saw that Peter can actually be nimble and light on his feet when he wants to be and can shed weight. I think Vitali hasn't taken that tune-up fight for a reason- either he has it or he doesn't and he's looking to answer that question with a titleholder he can make some change from as opposed to some walking corpse for Vitali to look bad against. Persistent injuries don't get better with time. One's dual interests in boxing and political office shows a lack of focus for either- it's not like they're complimentary.
