TMA make sense in their historical context. The skills that you deride allowed those people to be regarded as the best in the context they were in. If they had fought Leonard or Dempsey, they may have gotten beat, or they may have kicked or grappled them, or they may have adapted their own training to deal with boxers.
Except we have data of what happened when those Karate and Kung fu experts met boxers and wrestlers.
It didn't go well for the former.
Boxing and wrestling has obviously improved since those old bouts. Someone earlier in this thread stated that TMAs have been "watered down" in the same period of time.
Put people in armour and striking becomes an inferior strategy. Royce won the first UFC doing stuff that would have gotten him killed on a medieval battlefield. And even today, martial arts are more useful in countries with strict gun control laws than, say, the US
It's fair to have a critical eye and say "this wouldn't work in the UFC because X". But I find that style comparisons often hit a limit where things are compared outside of their respective contexts. We end up with discussions that are as pointless as saying "are cars superior to screwdrivers?". And often, the real subtext is "my style/dad can beat your style/dad therefore I am better". That's playground-level discussion.
People refine their methods based on their goals and context. You know how William E. Fairbairn reinvigorated Western combatives? By incorporating Japanese Jujutsu...
Well why wouldn't it be fair to compare GJJ to Wing Chun for example? Both are modern martial arts designed for general self defense and self improvement. I wouldn't consider that a comparison of a car and a screw driver. Instead, I would say that you're looking at two types of cars and their overall performance.
And yeah, Royce's style probably wouldn't have done very good against a samurai, but it worked really good when a huge wrestler pinned him to the mat and tried to bash his head in. Interestingly, those same techniques worked really good for me when a huge guy tried to bash my head in too.
