Interconference Results
I'm not a fan of arguments about which is the "best" conference, but since they're going to happen anyway there may as well be some data to back some of them up.
Of course, there are many ways to examine an interconference "resume" including the same results-vs-opponents' ranks we use for teams.

Computer Composite Poll

Often people who are not familiar with the nature and limitations of statistical methods tend to expect too much of the rating system. Ratings provide merely a comparison of performances, no more and no less. The measurement of the performance of an individual is always made relative to the performance of his competitors and both the performance of the player and of his opponents are subject to much the same random fluctuations. The measurement of the rating of an individual might well be compared with the measurement of the position of a cork bobbing up and down on the surface of agitated water with a yard stick tied to a rope and which is swaying in the wind.
