125: Demetrious Johnson - he barely scrapped Ian McCall and Benavidez, then flicked a switch and made them all look like crap.
135: TJ Dillashaw
145: Max Holloway
155: Tough one. I would say Khabib, but Ferguson has really come into his own since his debut. Maybe RDA too.
175: Covington
185: Whittaker
205: DC? Jan Blachowicz?
265: Volkov - no way he would have beaten Nelson and Werdum when he was still fighting in Bellator.
