With the NCAA tournament, do people really care about either? I'd bet most couldn't name the regular season conference champions of most other P6 conferences.I could make an argument that the conference tournament is more “important” but the regular season title is the title that absolutely matters in determining who the conference champion is and, at least in terms of P6 conferences, is the one people care about.
The best part of the regular season championship is the overall record that generally comes with it. Then again, I'd rather be 2012 Colorado than 2012 Washington.
