pure puncher i will go with pavlik...I like wlad in hw and lennox...cintron can punch too just cant beat margarito
Guys like Arce, Wlad, Darchinyan, Corrales, Raf Marquez, Munoz, Hamed and Tua deserve a mention. Besides the obvious choice in Pac. Edit: How could I forget Tito, nice one Gonz
Pavlik is not a one punch knockout guy despite his gaudy KO percentage. Id go with Antwun Echols, Kostya Tzyu, Pac, Rafael Marquez, Alexander Munoz, David Tua
Come to think of it, Roy Jones likely deserves a mention among these other names. Check his rematch with Griffin for an example of him carrying that power up in weight divisions. He has a lot of brilliant one-shotters. Edit: He didn't always elect to bang, but he sure had power when he did show it.
