One legged wrestler. Dis-advantage, or advantage? What's your opinion?

At first glance, one would think that a wrestler with 1 leg would be at a dis-advantage, but is this really the case?  If you think about it, a human leg weighs around 20 pounds.  This actually gives a 1 legged wrestler a distict advantage within his weight class.  That's 20 more pounds of upper body strength that a 1 legged wrestler can have.  So, the question is, does a 1 legged wrestler have a dis-sdvantage?  I don't think so.  He is fighting within a weight class that he should not be fighting in.  He should have to fight in a class 20 pounds heavier than he is to be an even matchup.  So is it cheating to fight below your weight class, I believe it is.  If you look at enough pictures of the Arizona State wrestler, you can plainly see that he has much more upper body strength than his opponets.  Don't get me wrong, it's an incredible accomplishment, but is it really fair?
