This one is going to be US-centric, but if they're vocal about how they only care about college sports specifically and aren't a fan of pro sports there's a substantial chance they're a horrible reactionary and probably worse than your average chud.

I'm interested to see how the effects of things like the NIL in college sports (players are now legally getting paid through boosters of colleges as a short summary) will impact these people's fandom (if at all) in the future. This is interesting as their "defense" has always been about how it's been a more "pure" form of the game without players getting paid which I'm fairly certain is just thinly-veiled racism.
