D-1 football used to have a sound and objective metric, but, because 1,000,000 X more people looked at it, and went apoplectic when TCU overtook whomever when both teams won their final RS games a few years back, the NCAA caved to the outcry from the ignorami...
That was about a flip-flop via SOS, and SOS matters.
If we looked at D-3 hockey right now based on historical success and "name brand", Hobart would easily pass MY eye-test, but the eye-test doesn't matter.
The PW is imperfect, as is the RPI, and they are generally identical in their results... But they're not bad. The KRACH was easily the most predictive metric, but people don't generally grasp statistical regression, so the NCAA dumbs it down for them... IMO, the KRACH calculus should be the gold standard in *every* NCAA sport.
But, we have a horse-race here, and that's fun. I wouldn't mind Endicott garnering the overall #1 seed, if they keep winning. The margins are razor-thin among the current top top five. Looks like a fluid and entertaining finish to the RS.
