Gamboa, just. But he doesn't dig in with his shots like Pac does.

As a side note this thread got me thinking about Roy Jones speed and power in his prime. He reminded me of both these guys mixed and amazingly I think his handspeed is equal to these 2 despite being a hell of a lot bigger. Maybe I'm just being a fanboy of my favourite all time fighter but i'd be interested to see if Roy could throw as many punches per second as these 2. I think he would!
