I’ll clarify for you, since it seems like you are having trouble understanding what I said, including confusing the meaning of strategy and tactic.

Strategy: Try to generate as many quality 3pt looks for your shooters as you can.
Tactics: The little things you do to generate those quality looks.

Outcome: On average, a higher 3pt% than expected.

Variance: If your team shoots 43+% over a 7-game series, there are likely to be some where you shoot over 50% and you are likely to win those games. In their last 9 playoff games vs. the Celts, the Heat shot over 50% from 3 four times, and won all four games. They are 1-4 in the five games where they shot under 50%.

Just because you have a strategy and tactics, it doesn’t mean you will succesfully execute it. Seems like Spo’s team executes it quite well in the playoffs, and quite often.

In last year’s playoff series vs. the Celts, the Heat shot 43.4% from 3. Their wins included:

Game 1: 51.6%
Game 3: 54.3%
Game 7: 50.0%

It’s definitely a strategy, and it worked last year to perfection. Spo seems to give his guys outsized confidence that if they execute his game plan and fire away, they will be successful. It will probably not win them this series because of the on-paper talent differential, but today’s game was not an outlier. The Heat, especially without Jimmy, are even more dependent on seeking and making open 3’s than they were last year.
