The quad wins as a means of sorting data as a starting point is actually quite good. Building in road wins into the quads made perfect sense due to unbalanced schedules. And as I said, nobody is equating all quad 1 wins, it is merely a start for the anlysis or discussion of bubble teams. Now in the middle of the bracket where they spend little time they basically just look at # of wins and that is it. But not at the bubble level.
To me the major flaw remains that RPI is still at the heart of this. The RPI has a multiplier effect that is larger than other systems, and it will unjustly elevate or crush some conferences. For example the SEC has many more quality win opportunities than the B10.
Is the SEC better this year? Sure. But it only has 5 of the top 40 teams in KenPom. But its RPI is out of whack, which is creating way too many quality victories for some of their schools.
If they just used KP/BPI to rank the quality of a victory within the quad system, you would see resumes would be quite different.
