Guess we'd better do the F+ rankings. And given the discussion of Buffalo as a program let's really dig back for context.
Pre-2005 (when F+ numbers start) - Buffalo had no team from 1971-76, played in D3 until 1992, 1-AA until 1999, and then had a MAC record of 6-42 from 1999-2004. Very rightly considered among the very weakest programs in all of FBS at that time.
