Utah, Minnesota, BYU, Pittsburgh, Boston College, UConn, Nebraska, Indiana, Penn State, Creighton, Gonzaga, Kansas, Wichita State, Maryland, Illinois, Purdue, Eastern Michigan, St. John's, Ohio State, West Virginia, Maine, Notre Dame, Cincinnati, South Dakota State, North Dakota State, North Dakota, Rutgers, Harvard, Yale, Northern Illinois, Buffalo, Iowa, Northwestern, Michigan, Air Force and Northern Colorado all have baseball teams. The PAC-NW schools aren't exactly bastions of warmth, either.
CU would spend the first 2-3 weeks playing games in CA, TX or AZ. Tons of teams do the same thing.
I'm not arguing that... I'm just saying the "elite" teams seem to all be in warm weather states.
