best punch KOs in UFC history?

[Righteous Jon]

That looks a ton like Rashad vs. Chuck imo.

 

[TeejayMac]

My favorites have got to be JDS on Werdum and Hendo on Bisping.

 

[gonads20]

 

[Viper98]

that's not a knock out
that's a knock down
7/10 times at least that fight doesn't get stopped it was just the ref positioning made it look like griffin was out

 

[Suicide Season]

Condit/Hardy stands out as my favourite.
