Precisely. Shooting lots of threes with good/decent efficiency also made two pointers more likely as more players would be defending the perimeter. Again, seemingly nobody thought of this for decades.
Then why the first time someone tried it then it worked and it stuck for 15 years or so? Last season there were 35 3p attemtps per game on average vs 18 in the year before Curry’s debut, almost 2x.
It it really impossible to think that it was a huge oversight?
You can’t just tell your players to start jacking more threes and coast your way to success. Many tried, many failed. The game is more complex than that.
