To the FightMatrix system, the most noteworthy match is based on cumulative rank strength accompanied by divisional strength.
In 2011, the most “noteworthy” match was: Frankie Edgar KO(4) Gray Maynard.
This saw the #1 versus the #2, for the most important championship in the deepest division (at least by number of competitors). The only other #1 vs. #2 in 2011 (in the men’s — at least) was the first match between Edgar and Maynard.
