1. Be careful where you get your info. The quote from the NCAA is a bit different, but has way different meaning.
The quote from the NCAA is:
"The NCAA has developed a new ranking system to replace the RPI as the primary sorting tool for evaluating teams during the Division I men’s basketball season."

2. You said they would be near the tournament cutoff. There is no cutoff, but if you think they will not go past 67 then neither will even be considered.
3. You said it was because of efficiency, I said there are other reasons.
4. KenPom is pretty much pure efficiency, but it also includes a factor for road vs home games similar to the RPI. Efficiency is also equivalent to wins and losses because the more efficient team will win. So even if KenPom doesn't count actual wins and losses they are inherently included in the formula.
Basically what I'm saying is KenPom includes most of the same factors as NET so of course they will be highly correlated. That shouldn't be news to anyone. The only differences would be the weighting of each factor. When the coaches asked for this they knew exactly what they were getting. Anyone with a college math class under their belt could have told them it would look a lot like KenPom if those were the factors they were going to use.
5. Seems relevant to see how it is used for selection, and see what it looks like after all of the data is included. Every formula has outliers at this point.
