This fight was vivisection, but post tap was truly when Conor's soul got snatched.
The look of relief and dog-like panting when Herb physically separates Khabib.
The cowering under then behind Herb's legs, totally gassed, offering zero resistance.
No indication at all that he'd able to defend himself if Khabib got past Herb and attacked him.
The way he looked up at Khabib from the seated stance, then looks away in shame.
The look away is the clincher.
It was very much the reaction of a beta wolf who loses a fight to the pack leader, and skulks away to lick its wounds.
I remember watching this the night of and thinking Conor would never be the same again. I imagine a lot us did.
