Why do guys in high school not like to date girls who are in the grade below them?

I heard a guy tell his friend (both are seniors) to not go for a girl who’s a sophomore. But why it’s only like a 1-2 year difference.

Also should add that it’s fine for them to legally date someone 1-2 years older or younger so why do they prefer not to date younger girls?
