Across college athletics, there are several instances of small differences in the men's and women's version of a sport.
Ice hockey’s biggest divide is the presence of checking in the men’s game, and then its absence on the women’s side. Even in basketball, men’s teams compete in two 20-minute halves as compared to women’s teams competing in four 10-minute quarters. The nuances also stretch into lacrosse, where men’s sticks have a deep mesh pocket and women’s sticks have a tightly-pulled pocket.
But an entirely different calendar and model? That’s almost unheard of in the NCAA.
