Pavlik has that great accumulative thudding power like Vitali with deceptive quickness. It is the type of power that after a few rounds any one of the punches can drop you.
I think Pavlik is kinda like Cotto. They both wear down their oppents with their power. Top Rank have Two really good fighters for the future.
I like his style and I don't see many flaws in him other than his lack of speed. If he was faster, boy he would be much more dangerous (which is scary).
