Fedor fought 14 opponents that could be considered cans: Lagvilava, Lazarov, Takada, Apostolov, Schall, Yanagisawa, Hasdell, Haseman, Valavicius, Nagata, Ogawa, Kohsaka, Zulu, Choi
Goodridge and Fujita weren't quite cans but pretty low quality opponents. Coleman and Randleman were very old and very past it. Lindland was a MW.
As truly quality wins that leaves Nog 2x, CC, Sylvia, Arlovski, Herring, Schilt, Rogers, Babalu, and Hunt. I will throw Arona in there as well.
Quality resume but the weakest out of the top 4 GOATs(GSP, Anderson, Jones, Fedor).
