Most devastating knockout you ever saw?

I searched youtube for mine to link here, but it's not there. In the mid to late 80's, Pisa Finai knocked out Gary Lightbourne. Finai had him hurt to where Gary was on the other side of the ring in a daze. Finai bounced across the entire ring loading up the right hand and knocked him out cold. After 10 minutes they still were tending to Lightbourne on the canvass. fekix trinidad ko'ing yory boy campas 1994

Back in the day some WWF guy tried to have an actual boxing match against Butterbean at Wrestlemania and got KTFO. That was a classic. The WWF fired the guy (Bart Gunn) after that.

Paret-Griffith 3.

Not very known but brutal nonetheless. Leotis Martin knocks out Liston. Ah Manmachine, why didn't you post this one in my thread in Boxing History section. I completely forgot about this one. I should have had this in my vid. It was such a brutal knockout. Poor old Liston froze when that first right hand connected. Anyway, here are some of the most brutal KO's ever

Ibaebuchi-Byrd always comes to mind when i think about devestating knockouts although its mostly the first big hook along the ropes that is most impressive in that eventual tko.

I still have to say the single most devestating one punch KO that I have ever seen was Ann Wolfe vs Vonda Ward, the last thing to hit the ground was her feet! She looked like she was dead, eyes rolled back in her head. The Ref was crying, he thought she was dead or at least very close to it. There was total silence in the crowd, Vanda was out cold for over 10 minutes, and was actually carried out of the ring on a stretcher. VERY SCARY. It's on You Tube, just look it up. That KO is why Laila Ali never wanted any part of the 6 time Champion Ann Wolfe. Can't say I blame her, I watched Wolfe whip the crap out of a man in the ring sparring, he made it almost three rounds with her before calling it quits....

I've seen countless KO's, but two that come to mind quickly are Cooney-Norton and Ruddock-Dokes. You can't get much more brutal than that.

Hearns-Duran, Herol Graham-Julian Jackson

Hearns/Duran was pretty fucking brutal. Most brutal I can recall that didn't involve death.
