solis said after being ko'd by pac that his wife punches harder. ergo, gamboa hits harder than pac. simple logic.
Well, I do think Pac is a bit sturdier now without making the low weight classes. I think Pac today hits harder than Pac at 130, but is not a huge huge welter puncher. Gamboa IS a big puncher, he can stop you with one shot; Pac will eventually beat you to death. It's the difference between Tito and Oscar, in my opinion, but BOTH got knock outs, and sometimes opponents handled their power differently (Oscar never ever came close to hurting Hopkins, Tito snapped his head back at least twice, and it took a whole lot of beating for Oscar to crack Vargas whereas tito almost got him right away, whereas Mayorga ate Tito's shots a little bit better than he did Oscar's sharper ones, where oscar almost got him out of there in the first round.) For whatever reason Pac had a harder time imposing his unorthodox swarming Aaron Pryor style on Solis, but Gamboa had no problems imposing his unorthodox Jones/Hamed style. For whatever reason Gamboa hit Solis cleanly from the second round on, so it probably seemed harder to him, but both guys hit hard enough to where it really doesn't matter who actually has more one punch power.
