Regardless of what Tyson could or couldn't do vs. Lee, I think Lee would get destroyed in the ring with a modern day MMA fighter...Anderson Silva for example. If you don't believe me, watch some of the earliest MMA fights...These fights pitted guys of different skills and backgrounds against each other and no one was really rounded in more than one discipline. Some of the greatest martial artists in the world (world champions even) competed in those early fights and they all lost to a guy who looked like he ran a 7-11 in Royce Gracie. It didn't matter how fast the Karate, JKD, and TKD guys were on their feet or that they could locate pressure points and strike quickly, because Gracie was going to put you on your back and take you completely out of your element. Gracie's Jiu-Jitsu was so far advanced that he was virtually unbeatable by fighters of standup disciplines, as Lee would have been. Gracie changed the fighting landscape, much like Lee changed the world with his martial arts skills. I have no doubt that if Lee were to learn the craft of MMA, he'd be a bad dude. But if we took a time machine and threw Anderson Silva in the ring with Bruce Lee, and said 'no rules' Silva wins that fight 100 out of 100 times. Hands down.
Silva, for those who don't know:
