Karam Gaber is the most dynamic GR big man I've seen in my short time exposed to the sport. He's only 24. If there's anybody who could make non-wrestling fans sit up, take notice, and say "cool," its him.
Check out this highlight video from the Dave Schultz competiton:

There are more at that website, too.
I agree with you 100%. The guy is nasty, he looks like a machine. Another greco-wrestler I think is pretty nasty, especially in par terre is TC Dantzler.
Good stuff!
Good thread.
