ms, it's easy to game the RPI. There were a lot more problems when RPI decided NT bids.
Just schedule 10 non-conf away games, find a way to 14 wins, and poof......you've made it due to RPI.
I prefer the projection report - it most often picks the best teams. RPI is not the sole measure for choosing the best teams.
In D1 in real life, for instance, I believe New Mexico U. has the #2 RPI. Did they deserve a #1 seed? Nope.
It's easy to be upset when the ranking system is more mysterious and less formulaic - but trust me, there were MANY more complaints when we went just by RPI.
