Kreed, I think both points are true. And my ?? about whether money mattered was sarcasm.
Yes, the "big schools" have more money for recruiting, coaching, travel, etc., etc., etc., that's helped them gain more power.
And yes, the committees do clearly know which programs will draw the larger crowds. Teams near the .500 mark in "power conferences" are getting bids over 25+ win mid-majors. That's a crime. And it's only gotten worse. Ask the 26 win Akron Zips how they feel about getting completely shut out of the 2007 tournaments. And ask the 2016 Akron Zips how they feel about playing a road game at OSWho when they had an RPI that was about 40 points higher.
