Yesterday, the Boston College Eagles baseball team received news they'd made it into the NCAA Tournament field. It's BC's first trip to the NCAAs since 2009 -- a figure which points out some struggles, but also shows it's not impossible for the program to succeed.
It's not impossible for a Northeast program to succeed, particularly.
College baseball, as you already knew and/or figured, is typically dominated by teams and conferences in the South and West. Wichita State (1989) is the only non-Southern/Western team to win it all in the last 30 years, and the most recent before them was Ohio State in 1966.
