Bruce Lee was a great martial artist and legend. However, he would get beat up in MMA. It is impossible for another man just to run through other top notch fighters. Bruce Lee is the man, but MMA fighting is something he really hadn't seen. Assuming he would kick everyone's ass is probably the dumbest thing I've ever read. Bruce Lee would get beat up in MMA. He would have a chance to be good, but he'd be fighting at 135. If he fought bigger guys, he would get smashed. Even at 135, there is no guarantee he would even compete favorably.
