#3 Grappling
Conor McGregor has been time and again derided by his critics for, what they claim to be, a lack of grappling skills. Well, if only someone had sent McGregor the memo, perhaps he may not have been able to out-grapple several notable foes over the course of his career.
Despite blowing out his knee during his fight against a young Max Holloway, McGregor continued to soldier on--transitioning from a striking-oriented strategy to a more grappling-based route. Furthermore, McGregor also memorably out-grappled Eddie Alvarez as well as Nate Diaz--the latter in their rematch--stuffing Alvarez's takedowns, and going toe-to-toe with Diaz in the clinch.
Love him or hate him, one simply cannot deny that McGregor's grappling skills are in fact criminally underrated.
