Ironically, about half of my rp circle has been jocks. Actually, that means they are over represented. Im actually not surprised though. i guess its only ironic according to stereotype. Jocks and nerds are disproportionately likely to be the same people if you actually look into what the hormones that cause one or the other do and realize they are the same hormones. Testosterone mostly. Higher than typical levels of testosterone in utero is strongly linked to autism and other neuro atypicalities found more commonly in jocks and nerds. Also boosts intelligence. This is a mild effect but a broad one.
Then again, if by jock you literally mean "dumb brute" that not what im talking about. I guarantee you though that if you look at most trackstars you are going to see a lot of oddly high chem and math scores

(and more of them will secretly be d&d players like you than the english major with an "original character self insert do not steal" person).
Frankly i suppose im an example of this. Loved playing sports. Was far above average at performing them (i detest watching sports though. I do not get it when people get so riled up for the game they arent even playing. Its like zoomers and millenials with their d&d podcast fandoms. I dont get it. I get bored enough to pull out my own teeth.) and im a super nerd. STEM ALL THE WAY BABY.
