I haven't seen enough Rosenbloom. I guess he's an ATG slapper, but Calzaghe is the Manny Pacquiao of slapping--pound for pound the best fighter of all times ever (that slaps)
1.) Slapsie Maxie Rosenbloom (I think someone already mentioned?) 2.) Joe Calzaghe 3.) Chris Byrd 4.) Troy Rowland 5.) Sven Ottke (Or maybe the worst slapper...)
sum1 said haid haye how is david haye a slapper u mite nt like him but i reckon hes a fairly solid puncher
