Complete nonsense dude.
Against Holloway he used various jumping knees, side kicks, high kicks, hooks on the outside angle, inside angle....dominated him on the ground as well.
Since the second Diaz fight, McGregor's mostly cut out the superfluous movements and focused on his trusty boxing, if you pay attention. And boy has he gotten great.
But Holloway is a brawler. Conor won't have to worry about takedowns or defending on the ground because Holloway is not much of a threat there relative to the various opponents he's faced at LW.
Rewatch Holloway's fights with Aldo or even against Ricardo Lamas. Holloway still throws that sloppy right hook that catches short opponents sometimes and isn't very fast. He makes up for it with volume, but the problem is when he steps in that cage it will be McGregor who controls the rhythm and has the power to hurt him. It's McGregor who will get to the center first and establish the flow of the fight. And once Holloway backs off It would look very similar to the first fight, minus the excessive takedowns from McG.
Against McGregor, Holloway won't be pointing at the center of the ring and calling for a brawl,
