The "beat someone out of conference" argument is new. The committee used to treat all games the same. If you beat a 38 RPI team, that was a good win, whether the team was in the conference or out of it. A good win was a good win.
I am really suspicious of the advanced metrics, because they seem to have a big P5 bias in them. RPI is simple and fair.
The last 5 teams in didn't really deserve to be there, but I have a hard time getting too upset about the exclusions, most of whom didn't deserve to be there either. St. Bonaventure was the one exception. A winning record vs. Top 50 and Top 100 with as many games as they played is usually a guaranteed bid.
There is nothing simple or fair about the RPI. It's much more important to lose a road game by 60 to the #1 RPI team than beat the #50 RPI team at home. That is ridiculous and dumb.
