Personally i don't think the knock out menas much at all.

He was obviously told he needed a knock out to win so came out in the tenth round and went for it.

Diving in totally forgetting the basics. Lead with the jab, then follow it u, keep the right hand up. etc

He dropped that right hand like a novice would in desperation. I always knew he wasn't a welter weight. If you look at his shape going into that fight he looks fat on a boxing scale.
