FYI there's no hard and fast rule that says that jocks are dumb and that smart people can't be athletic.
There's a positive correlation between intelligence and athletic ability.
The problem we run into with collegiate/professional sport and with the ridiculous geniuses is that we're dealing with long tail problems.
Even if there's a positive correlation between IQ and athletic ability, running a 4.38 is a "long tail" thing. And if you can run a 4.38, nobody cares if you're a Rhodes Scholar or if you're dumber than a dog. Likewise if you have an IQ of 160, you're in the long tail. At that point nobody cares if you can run a 4.38 or if you're Stephen Hawking.
So we see dumb collegiate/professional athletes and dweebish uber-nerds, and assume that the correlation actually runs opposite to the reality. That there's an either/or involved. There isn't.
