HCA appears to be tied very closely to W-L record. Not necessarily overall postseason success.
Just strictly comparing the W-L records, Asheville does have a better 1 year, a better two year and a better three year winning %.
Asheville also features 25 cent beer night for all Saturday home games. Factor that in with the WIS game time of 2:00am and it's a fan favorite. While Northwestern only serves Pepsi and keeps their library open an hour longer on game nights.
