Holloway would lose badly. His defensive wrestling works well against similarly sized opponents. Khabib is bigger, stronger and is stronger than most welterweights I'd like to believe. Khabib would put a "grown man beating" on holloway. A striker vs a bigger stronger wrestler never turns out right. It'd be poirier all over again. NO! and this is why I'm kinda against him moving up. Eventually he'll have to face someone of this nature. Whether it's Islam, Kevin lee if he gets his shit together, arman, Gregor, whatever the case. Conor, as much as I hate him, as much I'd also pick holloway to beat his ass any day of the week, posed a better challenge against khabib, because striking power. Holloway has some power. He sat down on strikes and beat the fuck out of volkanovski in the rematch but unless he completely transforms his shit and goes super saiyan he's got nothing to deter khabib on the feet either.
