> Recently, teams have realized three-pointers have higher point value despite their lower scoring percentage. This was such an eye-opener for me. A high-stakes sport like basketball/the NBA went on for decades without realising the simple math that three pointers are more valuable than two-pointers if you just do the basic math. How many areas in our lives are yet to be optimised with really basic math?

One possibility is that there are more players who can make 3-point shots at a high enough percentage to make this true. Also, it depends on how good the defense is vs. 2-point shots; if that gets tighter, then the 3-point shot becomes more valuable.

Which also suggests how things may continue to evolve; the best defense vs. 3-point shots probably compromises your defense vs. 2-point shots, and eventually some team will "realize" that they can do better with _fewer_ 3-point shots.

Further complication comes from rebounds; the player taking the 3-point shot is less likely to be able to get the rebound if he misses, relative to a player trying to dunk it. So, the math is not trivial, and it depends on what the other team is expecting/guarding against, which might make it a non-linear system (i.e. constantly evolving over time).

There was a time when chess theory said that there was one perfect, optimal opening, and anything else was a mistake. It was sort of true, until everyone took it as a given, and then doing another opening meant your opponent wasn't as likely to be prepared for it.

4th down attempts in American football come to mind. Twenty years ago they were rare; mathematically they should be common.[1] Coaches have shifted with the math but not quite as dramatically as it suggests. [1] https://malteranalytics.github.io/nfl-4th-down/

It's such an arrogant comment. "Really basic math"? Do you think NBA coaches reached this conclusion like this: 1. A player can throw X 2-points in a game. 2. Or he can throw Y 3-points in a game. 3. 3Y > 2X, so we should just throw 3-points all the time. It's absolutely not what happened. And the reason teams didn't discovery the current strategy decades earlier was absolutely not that they couldn't do basic math.

In the 2008-2009 season, the year before Curry’s debut, the 3p percentage was 36% vs 2p percentage of 48%. If you took 100 shots of each you’d have 108 points vs 96 so yeah I consider that quite simple.

And call me naive maybe but not arrogant, I’ve never been called that in my life so it’s quite surprising to be called arrogant in HN where I know the average person is smarter than me.

I personally think the 3-point line needs to be uniform distance. It is 22 feet from the corner compared to ~24ish feet from the center.

My recommendation is to let the home team draw the 3-point line on their court like how baseball stadiums have different dimensions.

Disclaimer: I have only extremely limited exposure to this topic (I worked in sports analytics, attached to a team, quite awhile ago), so take it all as heavy speculation:

1) It seems like there’s a natural resistance to change driven by loss aversion; you see a similar pattern in the NFL with decisions like punting vs. going for it on fourth down. Even if the expected value is positive, the failures are given far more weight than the successes.

2) In general, there's a lot of skepticism toward analytics until they reach a tipping point where they’re impossible to ignore, at which point they take over completely and introduce shifts like the ones shown here.

Moneyball, for example, has plenty of anecdotes about front office staff and coaches dismissing analytics in favor of “gut instincts”—and that was in 2002! In baseball, a sport which adopted advanced analytics far faster than others (obviously in no small part due to teams like that As roster).

Even today, plenty of NBA personalities push back against analytics—Reggie Miller, for example, has been pretty vocal about his distaste for them. He's obviously increasingly alone in that opinion, but it can be really hard to break old habits.

This article presents a readable overview of today’s NBA trends, but IMO is too absolute in its judgment. Basketball is not a solved sport. There is still innovation, for example with OKC’s historically good defense that relies on playing 5 smaller but faster players. There are still good all-around players. There are still people that hit a lot of mid range shots. We have trends going the other way, sure, but they h…

It seems like a very brief and abrupt article. I can understand the part about strategy of three pointers. But how does all the technology and analytics actually change the game, besides "improving form"? Has it allowed better calculation shots with the best odds for a given player? Has it discovered other team's weaknesses to exploit? Etc

While there is obvious winning strategy, rule changes around salary caps have already limited any one team's ability to dominate like GSW did for a couple years.

They mention Boston Celtics, but they are only a single time champion, and we can see plenty other teams with good chances to beat them.

And I'd argue we are moving further away from specialization: now centers are required to shoot 3 pointers at a high clip and high percentage, they have high number of assists (it's not just Jokic, look at Iannis, Sabonis...).

And centers need to defend smaller, faster players when switching, just like smaller players need to defend centers.
