The grappling defence was OK, he didn't get ground and pounded or choked, but otherwise I agree, he's made his money and is done fighting real opponents. Here are some stats. After his dominant performance against Eddie Alvarez in November 2016, Conor has had only 3 MMA fights, including this one. One with Khabib, which he lost, one with Cerrone, which he won (Cerrone, who is currently on a 4 fight losing streak), and Poirier, who he lost to and got his KO'ed for the first time.
Poirier in comparison has had 9 fights since November 2016, he's more active, he's seen the game evolve to where calf kicks are now a staple/new addition to MMA. Hooker uses them, Chandler knew to avoid them, Poirier uses them, everyone (Volkanovski, Adesanya, Gaethje, Marlon Vera, and so on) knows and uses them. Conor hasn't seen the game change from in the ring.
I'm sure Dana will throw him out yearly with the hype machine in full swing against a fighter who is safe for a big payday, but otherwise I think he's on his way out. He's stuck with the same team as well, so it's not him doing something retarded like Tony Ferguson, he's just not doing it seriously once he's made his money.
