probably floyd mayweather or roy jones but just normal IQ it definately wouldn't be mayweather i've seen him sometimes struggle to put a good sentence together.
bernard hopkins joe calzaghe (he was able to figure out nard during the later rounds) mayweather (boxing iq and athleticism combined) gerry penalosa (no doubt) cristian mijares juan manuel marquez marco antonio barrera
I was about to say the same. Even though he doesn't fight like he has a lot of brains. He is apparently not really using them in the ring...
