Okay, everything you've written is correct and accurate, and I respect that you spent time on the research and did your homework, but I guess I honestly don't see what your end point is.
No more mid-majors in the tournament, no matter how well they do in the regular season? Only Power 5 teams in the tournament since they play the toughest schedules?
I'm honestly not trying to put words in your mouth (or whatever the posting equivalent is), but I don't know what argument you're trying to win here.
Oh no... I love mid-major teams in the NCAA Tournament. They bring a completely different flavor and add drama as the tournament unfolds each year. I mean... watching teams like 11 seed George Mason, 8 seed Butler, and 11 seed VCU make crazy runs to the Final Four was awesome. Other teams pulling off shocking upsets like 15 seed Florida Gulf Coast making the Sweet 16, 13 seed LaSalle making the Sweet 16, or 1 game wonders like Norfolk State knocking off #2 seed Mizzou, Lehigh knocking off #2 seed Duke, Northwestern State knocking off #3 seed Iowa, Bucknell knocking off #3 seed Kansas, UNI knocking off #3 seed Mizzou 25 years ago... etc... Those games are what the tournament is all about.
My issue is with the more recent trend that the selection committee is on where some of these mid-major teams are being seeded far too high.
Compare these 3 resumes and tell me which team should be the #1 seed... (Quality wins are only against ranked teams)
Team A
Record 30-2
Regular season conference champions and tourney champions
Quality wins - @#22 Oklahoma State 69-68
Strength of Schedule - 96th
RPI - 6th
Team B
Record 27-5
Quality wins - #3 Kentucky 75-68, #2 Louisville 76-71, #4 Ohio State 73-68, #5 Miami(FL) 79-76
Strength of Schedule - 1st
RPI - 1st
Team C
Record 27-6
Regular season conference champions
Quality wins - #13 Michigan State 67-59, #1 Duke 90-63, @ #19 NC State 79-78,
Strength of Schedule - 7th
RPI - 4th
In my opinion Team B clearly has the best resume of these 3 teams.
