Frankie Edgar has had an incredible career, only losing fights against guys that should be a weight class higher. He fought Aldo to a very close decision, and Aldo walks around 10-15 pounds heavier than Edgar. I believe if Frankie had been fighting at the weight class he could/should've, he'd have a lot of title defenses. (He's the same size as many 135'ers.
After Jones, Fedor, GSP, Andy, Aldo, and MM, could Frankie be 7th greatest ever? Possibly yes.
