I thought is was pretty obvious what I was saying there - the cut ended the fight because Machida was fighting mostly blind after it. You really think it's some sort of complete coincidence he got dropped almost immediately after the cut happened??
Machida himself admitted he lost his confidence after the cut. Also the punch that Jones countered was a wild hook by Machida - that's clearly not Machida's normal way of fighting.
On top of that, the distance that Machida was throwing that hook from was very poor - Machida normally has great distance, but the cut probably affected his ability to judge distance accurately.
I think Machida went into desperation mode after the cut because he probably figured that unless he landed a big haymaker, he was going to lose due to not being able to see shit. Jones easily countered Machida's wild haymaker thus dropping him, then choked his ass out.
Of course all this means little, I still think Jones would have won the fight anyway, he's the superior fighter to Machida. But to say the cut played no part in the finish is absolutely silly, IMO.
