I was just reading Matt Hughes' site and it has this Ask Matt section (
http://www.matt-hughes.com/askmatt.html). Here's an excerpt:
"What are your max out weights for bench, squat, deadlift, etc? -Steven
I do not max out anymore, and have not for a long time.
Years ago: bench - 310, squat - 375, deadlift - 425
I get a lot of my power from my back, and body position.
I can take a 240 pound guy, who would beat me in every lift badly, and grapple him and make him feel weak. I call that usable power and that has to do with body position and leverage. -Matt"
If he is talking about regular people then I would believe that, but it is hard to believe he would make a 240lbs professional fighter feel weak, maybe he bases this expierence from grappling with Tim Sylvia.
