That is an interesting comparison, however the sports field is where a human is in his or her optimum environment.
In an aircraft the human body is most definitely out of our ideal environment. Our sensory organs are ill suited. Our balance organs have no way to give us situational awareness, in fact they give us false information which we must learn to supress and instead monitor instruments that require conscious thought rather than subconscious action like on a sports field.
If we were birds you would have a more valid point, however even they have the same problem as a human when it comes to damage.
We learn using muscle memory and by practise. A change in our fitness level or mobility takes us a long time to adapt to. By contrast, computers have almost instantaneous feedback loops and adapt very quickly as showm by the NASA neural net trials for control adaption after damage.
The simple fact is that computers are faster at computing angles etc.
This is obvious when you consider the type of fully autonomous aircraft that has been flying very successfully for a long time.

Fancy controlling those angles by hand?
