Edgar was given an immediate rematch when he lost the title to Henderson.
Then, after losing that rematch, he was given an immediate title shot against Aldo at 145.
Which he lost.
For Edgar to now begrudge Aldo getting the rematch against Conor, or to claim that he isn't being treated "fairly" by the promotion, just sort of shows you the character and class of Frankie Edgar. The guy is shameless I guess.
