The Power 5 D1 conferences are SEC, ACC, Bug10, Big12, Pac12. Schools in those conferences are referred to as P5 and they include all the blue blood college sports programs. The schools in non-P5 conferences (American Athletic, Sunbelt, Atlantic 10, WAC, etc.) that compete in D1 athletics are referred to as mid-majors. This would include schools like Boise State, UNLV, Texas State, Southern Miss, Coastal Carolina, Davidson, etc. When it comes to college baseball, many mid-majors are more competitive that P5 schools at the bottom of their conference - with the exception of the SEC.
