... last year most teams took between ~18 and 26 5 ft to 19 ft jumpers in a game.

Like you said, small sample size, but a few teams definitely topped that by a lot so far. Boston took 36 jumpers in that range. Spurs took 31. Brooklyn and Orlando took 29.

Outside of that, most teams more or less are falling within last year's range in the very small sample size. It'll be interesting to see which trends continue and which ones fall off.
