Having a degree (or degrees) is a mark of *a certain sort of intelligence*.
I do consider myself of above average in certain measures of intelligence, and having a first class degree from, for instance, a university generally acknowledged to be academically very rigorous, and what I've done having gained that degree (small as it is yet!), is some evidence of that. I also know people from my university days who were definitely better educated, with more impressive academic accolades, who are now unemployed and seemingly unemployable).
But my game-playing or sporting intelligence is next to nothing. One would never ask me to play football for England or France (in fact I'd probably drop them if I only had to carry water bottles).
If this answer sounds self centred it's just an example lol
