Saw some people get upset at the lucky shot thing. I don't think the kick was lucky, he probably practiced it for many many hours. But the area of impact surely was lucky, I don't for a second believe he anticipated Mousasi leaning in like that.
There's definitely some luck involved in how that landed. And he finished it off beautifully with the knee.
I wasn't really thinking we'd ever see the day where Mousasi would get finished by strikes anymore.
A lot of times, as a combat sports fan, it seems like those shots to the side of the head, especially with kicks, are very devastating even against a guy like Mousasi who can take hard shots on the chin without issue. I don't know if there's science behind it but it seems like they disrupt motor control instead of KO'ing like a strike that hits the chin? When GSP got TKO'ed by Matt Serra, for instance, it was a hook to the back/side of his head that did the initial damage. Gegard was on wobbly legs immediately but he'd have recovered if not for the knee.
But yeah, I agree, there was some luck in where that kick landed. Mousasi was leaning in, and it landed with a huge amount of force. What an upset!
