I am not sure what you are talking about, because the score already has been settled once and for all.
The fight was not even close. Khabib absolutely dominated Conor, decimated Conor, humiliated Conor, who QUIT ... leaving him a tired, beaten, broken man, who remained sitting on his ass in the wake of defeat.
Khabib has gone on to defend his title, the moment he was allowed to fight again, while Conor can't seem to muster a single return event.
Conor's true inner self-confidence is destroyed. He barks publicly on Twitter, but deep down inside he is now gun shy.
You need to realize that Khabib is interested in his legacy. Beating Tony Ferguson enhances his legacy. Exiting the game with a victory over GSP cements his legacy.
Beating Conor again does nothing for Khabib, besides waste three months' training time just to gain not one iota more toward his place in history.
He does not have to absolutely smash Conor one more time. There's nothing left to prove, as he took Conor's soul, the last bit of fighting spirit out of him, the first time.
