I'm still surprised Duran started to get up after that atomic right hand Hearns flattened him with. Hearns vs Duran Marquez vs Pacquiao Martinez vs Williams Tyson vs Spinks Alvarez vs Kirkland Jones jr vs Sewano Tszyu vs Bergman Pacquiao vs Hatton Golovkin vs Macklin body shot KO Matthysse vs Peterson Froch vs Groves 2
Abraham Koing Gevor. I actually thought Gevor is dead for a moment. https://www.youtube.com/watch?v=XGQfadN_10Y
Jackson v Graham is my all-time favourite. The most brutal TKO I've ever seen was Tito v Yory Boy Campas. Campas was completely separated from his senses, his eyes rolling into the back of his head and if the ref didn't jump in, he could have suffered some serious long term damage.

Wait. There are too many to post now that I think about it lol...
