His top game is high level and his bottom game is fair. His TDD is actually pretty good. The biggest issue is his TDD is good for 8 minutes. Eddie Bravo has even said Conors bjj is legit as fuck, and Eddie doesn't have skin in the game.
Tbh his first round against Khabib was impressive defensive wise compared to all of Khabib's recent opponents. Took Khabib 4 minutes to get Conors back to the mat, let alone work from top position. Compare that to Dustin who had his back taken and Barboza who literally got prison raped the whole first round.
