Assuming the thread originator meant 160, because at 168 there many fighters (Calzaghe, Kessler, Mundine, Bute) who could beat, I see Taylor in a rematch and maybe Abraham as having the only shots to beat him. To tell you the truth Abraham didnt impress me much in his questionable decision over Miranda, which really should have been a tko loss. Pavlik applies better pressure and has more power and stamina than Miranda. I think he would pummel Abraham into submission, unless Abraham was able to stick and move all night long.
This implies a decision outcome. I do not think it will be a decision either way. Either Abraham jumps him and finishes Pavlik off - and he can do it better then Taylor, or he is out before 9.
