Do you mean the 8th round? I was thinking that myself. If there ever was time to score a 10-8 w/ no KD then the 8th round was it.
this...^ but Matthysse still won the fight without the extra point, sadly the judges robbed him a second time...
Alexander wasn't running the whole round while out on his feet. Think Khan vs. Maidana, round 10. THAT was a clear 10-8 round. I don't think it was enough to justify a 10-8 round because Alexander was still throwing back and landing.
He was never out on his feet. Even when he went down, he came back strong. He was more tired than hurt in rounds 7-8 if anything from Mathysse's body shots.
It was the 7th where I thought Alexander was one good punch away from going down again. And then he got hurt again to the body in the 8th.
