Hello.I would say yes.Particularly in the heavyweight and middleweight divisions.With the Ali era most of those fights today would have been stopped.The ref jumps in now at the slightest faulter due to health and safety.
Ali took batterings that no fighter would be allowed to take today.Hence the state of Ali now.God bless him.
The same with the Hagler ,Nigel Benn and the Eubank era.
Those days often the only way out for an exhausted fighter was to get knocked out.These days the ref will save it.So to answer your question.Yes.
On the contrary, there could be more knockouts now despite the waiver on the three knockdown rule, the reduction of championship fights to 12 rounds, among others because of:
1. Mismatches
2. It's easier to get rankings today due to the proliferation of the boxing alphabet soup organizations-- even the untested and unproven could not only get rating but even cracks at the champions of the diverse titles, therefore the greater likelihood of them losing by KO/TKO.
3. Undetected illegal use of PEDs.
4. More boxing deaths and injuries despite better health and safety protocols.
Though I don't know much about boxing, I would assume so for several reasons;
1. Increased awareness/prevention of TBI (traumatic brain injury)
2. Tighter refereeing regulations and guidelines
3. Increasingly padded gloves
4. An increase in biologically smaller athletes (Hispanic/Latino People's) means less power per punch
Just my guesses based on logic.
No that's like saying are there less injuries because safer equipment, can you run faster because your shoe is lighter. There are always knockout just some boxers like heavy weight are support to knock you out.
I would imagine not. Although I think that boxing defence has evolved more being a boxer myself.
No, why would any one think different?
Compared to the Muhammad Ali era? What about 10- 20 years ago?
