What I can say that I don’t want is a coach chosen to overperformance of a mid-major in this tournament. I think the smaller schools are benefiting from two huge factors:
Small number of fans levels the playing field a lot. Big schools get an almost home court advantage in early round games is usual years
Bad NBA draft class. We know this because UK and Duke sucked. When the draft class is bad, veteran well-coached teams can overcome the talent advantage.
