Do you mean ones that reflect their teams that state “No class?”
If they allow such then why not advertising? Where do they draw the line?
It is simply amazing that the NCAA turns a blind eye to the cheating going on in college basketball, and when it catches certain schools just gives them a slap on the wrist (UNC no work classes for 18+ years) or mild reprimand, or if there are allegations about cheating (Duke recruitment of Zion Williamson) at certain schools, refuses to investigate. But they are all over this politicization of sports through the social justice warrior racialist incitement programs.
If they allow advertising for sjw causes, they need to allow advertising for conservative causes.
