My exhaustive scientific studies have shown that men who do not follow sports do so because their minds are preoccupied with homoeroticism, or soccer.
As such, they are unable to focus on the competition. Example: a normal person sees a highly competitive NBA Finals game between two elite teams. The score changes, the hit shots, the critical misses, all culminating in an eventual champion.
Contrarily, the male non-sports fan sees an entire team of 6'7" black basketball players spit-roasting him in the club showers. Or some other homoerotic scenario.
He will focus on anything to avoid showing obvious arousal in public.
"Anyone want chips?" "Oh, I need to make this call." "Your wife need help in the kitchen?"
Be wary of the non-sports fan, for inside every one hides society's true enemy, the homosexual.
