No one else has ever blown out Sprott like that as far as I know. Not too bad considering how durable Sprott is, and I think Sander's was pretty green at the time.
The most brutal fight that ever took place is Nelson Wolgast II. 42 rounds 80+ punches per round from each fighter. Both ended up basket cases.
Oh Jeez. There have been a few. Watt-O'Grady was rather brutal, and one of the bloodiest fights in history. Gomez-Pintor Chacon-Boza II Chacon-Limon IV The Vasquez-Marquez trilogy Somsak Sithchatchawal- Mayhar Monshipour (not a lot of blood, but still...) Dorin-Balbi I The list goes on and on...
Yup. I enjoy the ebb and flow of great fighters, even occasional brutality... But that fight was almost impossible to watch. Everyone involved saw it and they put a stop to it. Trevor Berbick vs. Bobby Crabtree is a one sided beating that I was genuinely wondering if Crabtree was going to survive. He had absolutely no defense, the ref was unbelievably leniant... Berbick landed dozens and dozens if not hundreds of flush power shots, every single one landing completely flush on someone who never even learned how to block a punch. Ugh.
