I think we're talking about a little bit different type of slam here. I don't know the ultimate fighter's name (probably 6 years ago), but the best slam I ever saw was in a championship match. He shot in on a double-leg, went airborne, planted the guy on the mat, and came down with his shoulder in the guy's throat. Of course it was over, and it was legal in UFC. You try that move even in college, and you're done.
