Depends on the actual definition used, which they have become fuzzier with the new realignment. The "new" big east is not a power conference, yet not really a mid-major either, but definitely not the high-major conference that it used to be under the "old" big east status. There are quite a few programs that were never considered mid-majors (e.g., Georgetown, Villanova, etc.) but at the same time I still have a hard time considering some of the new additions that were not part of the "old" big east (e.g., Creighton, Butler) as high-majors either.
