Is Leon Edwards headkick KO of Usman the cleanest 1 shot that ended a champ’s reign?

[Fioretti]

I gotta go with Stipe koing Werdum, it was a perfectly placed one punch ko while moving backwards

It doesn't qualify, there were follow up shots. Leon over Usman is literally the only true 1 shot walk-off KO.

Stipe over Werdum and Conor over Aldo are the next closest. Both had follow up. I just looked at all the champ threads and Leon wins.

The crowd were all excited thinking that Werdum had hurt Stipe and that Stipe was retreating. Then the place went silent like a funeral. Jan running full speed with his arms swinging versus Santos was similar. As was Ngannou versus Rozenstruik but Ngannou actually connected there. Zhang versus Andrade had a similar running flurry as well. So that not uncommon but seems like a high risk move.

Jan I didn't mind so much cause he throws that combination and it lands well most of the time. But he just threw is far out of range and lunged in.

Conor's 1 shot Ko and Holms are right there with Edwards, they both just followed up aggressively but it was not needed.

I sorta see a walk off as 1 guy still out cold and the other just walking away raising his hand. Conor followed up with some gnp and then the ref got in a knee. Didnt look as cool/clean as a headkick like leon was kicking a pad.

It took Leon 5 fucking rounds to land a lucky kick. Aldo was dead with or without Big John's shin. 9 seconds goddammit, what are you looking for?
