To be honest, I didn't really see any clear rounds for Pac. He landed one punch in the fourth which carried Mayweather into the ropes and then after a wild flurry which only hit Mayweather's arms, Pac backed off and proceeded to get jabbed and countered by Mayweather. That was the worse performance for a Mayweather opponent I have seen since Baldomir.
I thought there were 2 clear Pac rounds and 2 close rounds, one of which I have to Pac. I thought he still did more than Canelo or JMM though :conf
Canelo got a draw on one card. lol But you are right, I forgot about those fights. Pac may have done infinitesimally better than Alvarez or Marquez, depending on your viewpoint.
Ya I thought he did a little better than those 2 and exactly as well as Guerrero. At least there were 1 or 2 fleeting moments of discomfort for Floyd against Pac and Guerrero that I never saw in the JMM or Canelo fights. But I agree it was a cruise control fight. The Pac and Cotto fights underline your point perfectly about just how different two 9-3 fights can be.
