LOL. No, he didn't. The only top guy who fought who was top at the time was Chad "Mini Camp" Mendes, who was in Montana or something hunting when he got the call, and rolled into camp on 7 days notice I think?
Holloway certainly looks good on his resume, but he got Max before Max was great.
The top 5 when Conor was coming up, were
1) Aldo
2) Frankie
3) Mendes
4) Swanson
5) Lamas or Oliviera
Melendez was still in the mix then too, arguably top 5.
At the time Holloway was maybe 6. I'd rank Conor in that top 5 mind you, but other than Conor thats what your top 5 looked like 2-3 years ago.
He fought one guy out of the top 5, and the guy came in on a weeks notice. So no, he didn't run the gaunlet, let's see who he actually fought.
Marcus Brimage, who?
Max Holloway, great fighter now, but he wasn't ready then.
Diego Brandao, good win but the guy has never been top. 18-10 I think when he fought Conor. A good veteran, nothing more.
Dustin Poirier, good win, but the guy has never been top 5. Good eliminator fight.
Dennis Siver, he's a journeyman. Next.
Chad Mendes, the only top 5 guy he fought before Aldo.
Aldo, great win, but it didn't really tells us much about how they'd shake down without an instant flash KO, the way say, Max dismantled Jose exactly the same way in two fights.
No Lamas. No Edgar. No Oliviera. No Swanson. You run the gauntlet, you take out at least 3 of the top guys in the division.
I won't hold the 155 fight against him so much, because the UFC saw Eddie 'sloppy brawler' Alvarez had somehow stopped RDA, and saw an opportunity to build the hype around Conor even more. I don't think he was deserving of it, in a way that say GSP was deserving of fighting Bisping, but Bisping was the top fighter at 185 in much the same way Alvarez was. They were in the right place at the right time, got the job done, but any number of dudes at 155 and 185 would have smashed Alvarez or Bisping.
