I would lean toward Kessler UD, but if Taylor can out jab kessler he can easily win. I see whoever establishes a better jab wins.
I always felt that Taylor was weakening himself making 160 in his last few fights at that weight. I think just by the fact that he fought better in the rematch at 164 against Pavlik and now even looked better at 168 proved that. Even now I think maybe he should be fighting at 175. Lets not forget that he walks around at 185- 190.
