None of your arguments make sense. If Rutgers and OU were in the same conference, sure, you'd have a point. The Big 10 was the 4th best conference this year by RPI. You need advanced metrics, KenPom, NET to be able to accurately compare teams across different conferences who have different schedules. What's to say OU doesn't have a better record against the tournament teams Rutger's played?
Exactly. The metrics don’t care what conference you play in. The committee clearly did care which conference you play in. The metrics don’t evaluate teams as “in the tournament field” or “not in the tournament”, because humans are doing the tournament selections and using extreme bias in some cases. The metrics evaluate each team based on its results, not “eye test”. The year’s committee did a very poor job, because they didn’t use the metrics like they had been since 1993. They let their own biases determine the field of teams.
