I'd like Pavlik to win, 'cause I've become a big fan. But I'm not so sure it's a done deal. Taylor's got the hunger back, and IMO he possesses considerably more boxing skills than Pavlik. Can't underestimate two things, however: Pavlik's heart, and Taylor's memory of the previous KO.
All in all, though... my prediction is Taylor by UD. I think he boxes Pavlik smartly and avoids trading. I also think Pavlik underestimates Taylor's skills for this rematch. Taylor by UD.
