This was simply unimaginable even a couple years back when for decades ATP tennis had been considered a 20-something year olds' game.

To me, it really exemplifies that often it is better to slowly move into the right area, and save your resources for when it’s optimal to move quickly with a burst. I think a good analogy to this is when Warren Buffett talks about investing, he often talks about waiting for the right pitch. Often, the preparation might seem like no action or result in to action to the outside world, but enable you to be ready when the right situation arises.
I did mixed martial arts for 10 years and sparred with someone who eventually went on to be a semi finalist on The Ultimate Fighter. He easily destroyed me and he couldn’t make it in the UFC. How much more of an outlier is Khabib or Mcgregor? I did Ph.D. studies in mathematics at a group 1 reasearch imstituion. Went to a talk by a graduate student from Berkeley in the same area as me and in school for the same length of time as me. It was clear I would never know as much as him or be as good as him. I quit my Ph.D. program shortly afterwards. I knew I wasn’t good enough to do worthwhile research in math. Outliers among outliers.
That being said, I agree that you'll learn much more from reading books, taking a course, etc. than sitting down and watching sports for the equivalent amount of time.
I'm not sure that's true, game tapes - if strategically cut together - can be very effective in teaching strategy and individual techniques for sports. Video games can also be very effective in this regard. This works because it activates mirror neurons when you imagine you're doing the thing you're watching.
If you're looking to build expertise in a given sport, I agree that watching it is probably one of the best ways to do so.
Instead of thinking "what can I get?" just revel in the players own sense of joy and mastery.
Because sports is just as much entertainment as it is sports. These leagues need someone to be the face of their product in order to draw crowds and make money.
Jordan and the bulls were such a product of the 90s to save the NBA from the end of the lakers-celtics dominated 80s.
Gretkzy, like montana, was part of a super team through with the NHL and NFL built their brands and generated interest in the 80s.
Brady and a bunch of QBs were beneficiaries of the NFL's move toward more passing and increased scoring to generate interest. The NFL found out that most fans love passing and scoring while the few purists loved defense and the running game. So they changed the rules to handicap defenses, especially against the pass. Now every year, we get superhuman passing records being set.
Look at the curry, durant and the golden state warriors today. Beneficiaries of NBA's move to handicap defenses and allow more scoring - which is what NBA fans, especially fans overseas ( particularly china ) like.
The days of the dominant center in the NBA or the running back in NFL is over, until the climate shifts and the they need to rebrand the product.
All these "superhuman" statistics are a result of "sports" + "entertainment". It's partly earned through athletic prowess and it's also manufactured by rules changes, refs "managing" the game, etc.
Was gretzky that much better than messier ( his teammate ) or lemieux as the stats seem to imply? Absolutely not.
Was jordan that much better than pippen ( his teammate ) or dominique wilkins as the stats seem to imply? Absolutely not.
But someone has to be the face of the product the leagues are selling. And the NHL before gretzky and the NBA before jordan was facing problems which was magically solved by gretzky and jordan.

We live in an era where being a 40 year old quarterback is not only possible but can play at top 1%. An era where an NBA player who entered after highschool has played for more than 15 years and has not had a major injury despite playing nonstop and has single highhandedly put a no name basketball team on the map. An era where not one but two of the greatest soccer players have played and peaked at the same time.
And all this is happening as teams hire more Post Docs in Stats and Math to find the secret sauce that makes teams great or find ways to break the game in their favor.
If you like Wayne Gretzky I suggest you look up interviews regarding the work ethic and impressive mental skills of other top players like Kobe Bryant and Cristiano Ronaldo, these guys are geniuses in their field but are absolute work horses with incredible discipline.
