What's wrong with having the four teams who proved themselves the best all season now getting together for the big battle in April? Why fawn over "parity"? Or if you are going to be a parity worshiper, why not note that the four teams in the NC are all almost on par with losses, three having 2 losses and one team having 1.
Sorry to point this out to you but tomorrow is April, and that's when there is only four teams left in the running in the NCAA tournament, so if you want to offer your paeans to parity, you should be really happy instead of griping about the fact that some of the 349 WCBB teams are stronger than others.
