I also knew an incredibly good 97lbs (44kg) wrestler. He was technically much, much better than me, but I could throw him around like a rag doll so I always won.
With weight comes strength. Any competition that rewards strength but does not penalize weight will end up dominated by heavyweights. Westling is particularly brutal as weight itself is beneficial for inertia.
Really? This runs counter to what I've heard from BJJ and other martial arts practitioners -- that a trained fighter could beat an untrained fighter in a fair fight (ie. no weapons, eye gouging, etc) using technique any day. You're saying that doesn't hold for wrestling?
The NFL has 32 football teams. Any quarterback outside the top 10 or so is considered 'bad' by most people. Assuming each team has a backup quarterback, out of the 64 'best' people in the world to do that job, only the top ten are so are safe from being called 'bad at their job' on any given Sunday.
There's also a story about a UFC fighter who went 0-3, and people called him a terrible fighter. Someone from his hometown mentioned how he was the toughest guy in town and one day beat up 4 guys and 5 cops at a bar all by himself, and he was only a 155lb fighter.
EDIT: I think I may have uncharitably read your comment as being argumentative instead of informative.
I was more thinking outside the top 1% of any particular skill, for example when you're hiring a designer or sales staff in a normal company (as in, a not-1% company, such as a refrigerator manufacturer or something).
I'm willing to concede that if you're looking exclusively at top 1% or top 0.01% candidates, you may profit best by taking their innate abilities into account, but if you're trying to find a top 80% or top 70% candidate (if you're trying to play moneyball with your organization or something) I personally would weight the depth and breadth of experience most.
