Federal Agency or Basketball Conference?

This idea is stolen from Colin Cowherd, a pinhead on ESPN Radio, but even a blind pig finds the occasional acorn. I’m going to list a bunch of abbreviations below, and you tell me which are the initials of conferences in Division I basketball, which are agencies of the US Government, and which could be either.

For example, “MVC” would be the Missouri Valley Conference, which is a basketball conference, while “NACIC” would be the National Counter-Intelligence Center, a government agency. “ACC” could be either the Atlantic Coast Conference or the Air Combat Command.

The full list of twenty abbreviations is below the fold. When making guesses, please identify the relevant agency or conference. No Googling allowed.
