i think conor's pride is very hurt more than anything. plus he simply cannot get over the khabib loss/humiliation, and now dustin with the KO and broken leg, criticism, the memes, jake paul's chain etc...it's clearly getting to him.
This guy was always bragging about his 'mcgregor' name and heritage, but he LOST the war with Diaz, Floyd, Khabib and Poirier, despite all of his yapping cringeworhy bufffonery shit talk. Now, he's going off the rails, his spirit is broken. DC is right.
He's not helping himself with his pathetic arrogance and delusion, and will only continue this way as long as he is surrounded by booze, coke, and his yes men clowns.
