You ever see Ronda post fight after a loss? Paul Daley? Well, he could've done THAT.
No he couldnt
Because he seen how things went for them after it, they were hated for it
Instead he chose to mimic a fellow loud mouth in Mcgregor and be super humble no excuse "i take my loss like a man" charade as he seen that it actually gained him even more fans and he was universally praised for it
It really was the only way for him to go about it after being such a big mouth prior to the fight
