Bailey does have legit 1 shot power which is more then a lot of those guys can say. Vitali and Wlad should be excluded imo, it's P4P and pound for pound no way we can judge that. A lot of those KOs are produced by their size advantage, it's easier to eliminate them from the p4p power discussion.

I'm a big fan of Lopez, but I'm not sure he has fight changing power in 1 shot. Those 1st round KO's were just product of speed and accuracy more then anything. I mean he does have a punishing style at times and definitely wears you down and can put guys down at that weight but not like others.

Almost every single Colombian seems to have ridiculous power 1 shot power from Juan Urango, Jose Luis Herrera, Dinisio Miranda, Breidis Prescott, ect. there are others but each of those guys has explosive power even if they aren't great fighters. Valero is a whirlwind but he does pack a pretty big punch. Abraham definitely, tons of power. Carl Froch is crap but he is heavy handed. Darchinyan same deal. All those guys just seem to have brute clubbing power.

My pick (it's the wrong one almost assuredly) is Yuriorkis Gamboa. Gamboa is an absolute train wreck in the ring and he is going to have a sick highlight reel when he's done. He's explosive and I think he's the guy with the most power.
