Bruce was the best; thanks for this thread and thanks to everyone for all of the great posts.
As for the UFC guys vs. Bruce...IF one of the "grapplers" aka Gracie; managed to get him on the ground; MAYBE they would stand a chance...chances are they would have been KO'd trying to get close enough to get him on the ground. And even if on the ground, Bruce would likely have been to fast and limber to get caught in a hold that he couldn't overcome.
I remember an interview from the late 60's - early 70's - wherein Bruce was on a show with some other martial arts master; who stood up; took his fighting stance; and challenged Bruce to "push him out of his stance".
Bruce walked over to him, delivered his famous one inch punch; sending the guy reeling backwards and said, "I don't push".
Funny!
I looked for it to share it; but couldn't find it.
