If MO wants to put a stud wrestler out there and have him wrestle a guy that normally wrestles 2 classes above him, then that's their mistake. Maybe they don't realize how tough it is to wrestles up, even if you're top knotch.
The only person that can wrestle up effectively at a middle weight is Saitiev. The proof is in his '98 European Championship in which he wrestled up 24lbs from his normal weight of 74kg. If you're not Saitiev, and you're wrestling up 2 weight classes, then you might as well be Joe Blo and plan to go home early. That's no joke.
