That one guy gave him all sorts of trouble by boxing out of the south paw stance. He whipped him good for four rounds before getting choked out right at the end. What was that guys name, chael sonnen? Anyway, Pac is on a whole different level in boxing, so yeah, he wins in his sport. Silva beats him really quick in his. I would expect Pac to put it on "good" light heavyweight boxers like Derrick Harmon, and i think in a straight up boxing match Harmon would beat Silva pretty easily. MMA fight, whole different story unless pac gets very very very very lucky with his first left hand, because Silva is kind of easy to hit with the straight left from a stand up.
Lol, MMA guys use this arguments like kicks are harder than punches with no empirical support at all.
