Continuing to think for myself, and since this discussion has really peaked my curiosity, I asked myself who should be excluded from the tourney to put Pitt and Seton Hall in. Curiously (to me at least), it wouldn't be the schools who were on the bubble as evidenced by the First 4, it seems each of those four schools belonged. Oddly to me, the schools that I don't think belong were seeded 7th, 8th, 9th, and 9th by the committee. Those would be Texas, TCU, Mississippi St., and Michigan St. Looking at their resumes, I don't see incredible non-conference success. Mississippi St had a good couple of days in November in the Hall of Fame Tip-off, and Michigan St had that game where they blew out Baylor. Texas and TCU don't really have anything of note, nor do Pitt or Seton Hall, for that matter. None had a winning conference record except for Pitt and Seton Hall. None made a deep run in their conference tourney except for Pitt. Looking at records against the remaining schools in the tourney, Mississippi St had the best win%, going 2-2. Pitt has the most wins with 3, but admittedly two of those are against the "Cinderella" NC State team. Texas has zero such wins. I honestly don't see any reason for Texas and TCU to be in this tourney, and all Mississippi St has over Pitt or Seton Hall is they did well on November 18th and 19th. Michigan St has a few "good losses".
Bottomline, I don't see anything that screams these four schools are better than Pitt and Seton Hall, whereas I see good performance over a two and half month stretch in January, February, and the first half of March that says Seton Hall and Pitt do belong in the NCAA tourney.
