Sheesh, it's Mayweather without a doubt. Go watch Silva's boxing sparring at Wildcard gym, you can find it at dailymotion. Silva's so called "fast reaction" plainly sucked against a boxer he was sparring with. He was even clueless when he was drawn into inside fighting. He couldn't see the punches and his face got pounded.
Floyds been a boxer all his life He knows all the techniques and punches inside out That puts him at a massive advantage in telegraphing punches
But to compare their reaction is kinda dumb. PBF fights against guys with great punching technique and timing yet he can still be elusive. Silva on the other hand looks fast because of the sloppy non strikers he fights in MMA.
I think Silva is the best p4p fighter in UFC followed by St. Pierre. However, I don“t think he compares to Floyd skills nor speed, specially in reactions. The stakes are higher if you make a mistake in the UFC, but Floyd has faced much faster and difficult guys to counter than Silva.
Mayweather of course, and next time can we not compare to a gay porn star! It makes me a little uncomfortable:nono!
