I am not as familiar with MMA, to be honest, once GSP pretty much quit, I have no interest in it, but I think that styles make fights, regardless of whether it is boxing or MMA. May and Pac was never going to be a slug match, because as much as Pac may have wanted that, I can't see any boxer who could impose that kind of match Floyd. It is always Floyd who imposes his will on the other fighter, and his will is to counter punch and not get hit. There is a beauty in being so fast and good defensively that you do not get hit, but if you are looking for power punches and knock outs, I can see how that might not seem appealing. I'm a fan of Floyd and his style, so I was entertained. If I want to see someone fuck another person up, I will watch GGG. Kirkland vs. Canelo should have some fireworks.
My take on MMA: a guy can lay on top of another for practically the whole round, not even doing real damage, and win the round/fight. That shits only okay when GSP does it.
