From the NYT article:
"While that may not be a majority opinion, the four days of upheaval in college basketball showed that Minnesota does not need to be in the field. Nor does the eighth-place team in the Big East, or the seventh-place team in the Big 12."
first, that should be "did not need to be in the field". Hopefully, that changes for next year and beyond.
the reason for expansion beyond just conference winners was because of multiple top 10 teams in the "power conferences" ie 1974 NC State #2 Maryland #3. NC State won the ACC tournament, Maryland couldn't be invited to the NCAA tournament even though it was ranked well ahead of many other teams participating in the tournament that year
Expansion is a non sequitur. You're getting toward the center of the bell curve making it more difficult to chose between the last teams in and first teams out. Unless expansion goes to, say, 256 - so that we're well on the other side of the curve. This year suggests maybe 65 teams was a bit much to try and fill. I think the first outs would have been Illinois, Mississippi State and Virginia Tech - all power conferences
two of the more memorable "lower" seeds to win that come to mind were 6 seed NC State in 83 and 8 seed villanova in 85.
last mid major to be ranked #1 going into the tournament I think would be 56, San Francisco. Last mid majors to win Texas Western 66 (UTEP) and Loyola 63. If you're trying to crown a national champ, adding more mid majors goes against the data
I like watching the underdog win as much as the next guy. I just don't see data suggesting the process used today is flawed (more so than suggested alternatives)
got to listen to Mychal Thompson on LA sports radio last week. Nice to hear he still bleeds maroon and gold. But, he does sound a lot like the click and clack npr car guys to me.
