I'm not sure I understand your point. It's now the P4 (SEC, B12, B10 and ACC) that have a lot of power, though the ACC's influence is on the decline. The other 3 are powerhouse FB conferences with the SEC and B12 looking dominant in MCB as well. The B10 has looked like hoops imposters of late even though Purdue made it to the final game. That conference has Under-performed in the tournament the past few years, though continues to get lot of bids with that trend unlikely changing. SEC is looking crazy good and well deserved supported by their OOC results this year. If my memory serves me the top of the Big12 has held its own as well.
My point is although the committee leverages the metrics highly for many of the at large selections, they have shown a P4 bias when it comes to the last 4 to 6 selections. Last season SJU clearly had the metrics to make the field, but got snubbed. My recollection has been head scratching committee decisions, selecting B10 and ACC programs over BE programs with stronger resumes and what makes us believe it will be any different considering how poorly most of the BE teams performed during the pre-conference schedule.
I hope I'm wrong. I think it will take BE teams that finish 3 through 4 need to beat up on teams below them and also beat the teams that finish 1 and 2 at least once. Creighton, which was thought to be near the top of the BE already has 5 losses and lost to Georgetown, which hasn't really beaten any top OOC teams. Other than UConn and Marquette, the rest of the BE programs couldn't seem to get any Marquee out of conference wins to my knowledge. Just seems like a perfect storm of our conference to get snubbed again. They one thing that might prevent that from happening is the ACC not doing well either.
