Found this on reddit, I assume the guy's research is accurate. Basically tells you there is a lot of floof with the NET vs seeding. You're 2x more likely to be 3(!!) seeds higher/lower from expected than exactly what is expected - that's nuts.
NET is only part of seeding of course, I am sure they use KP/BT/BPI in some way as well, so they can have both "most deserving" and "strongest". Although looking at the teams that were jacked UP - they are all big power conference schools. 3 of the 4 DOWN were mid-majors. So apparently TV matters too...
If I get some time, I might take last years NET and BPI and see how those look vs seed given.
Of the 52 teams from the top 67 in the NET who made the tournament, only six teams were given their expected seed (Houston – 1, Alabama – 1, Texas – 2, Maryland -8, Illinois – 9, NC State – 11).
Ten teams were given seed positions 3 spots or better than their NET ranking suggests they should have gotten. (Pitt, Arizona St, Missouri, Northwestern, Miami, Indiana, Providence, Virginia, Kansas St., Xavier)
Four teams were given seed positions 3 spots or worse than their NET ranking suggests they should have gotten. The big losers here are Florida Atlantic (NET 13, seed 9) and Utah St (NET 18, seed 10). (Tennessee and Oral Roberts are the other two.)
