I wonder how much the wrist has bothered Tatum. He's shooting a career low in 3PT%, although it's very similar to last year's mark.
With a team like ours that is very good at 3PT shooting overall, is Tatum's shot selection an issue? Is he taking too many 3PTs? If he were more selective, would the team be better or worse? (The same concerns apply to JB, who is also shooting a career low from 3PT).
That said, even a mediocre 35% from 3PT roughly equates to 52.5% 2PT shooting (albeit with a lesser chance at FTs).
I don't think Tatum is in any singular way, the problem or the main problem. Our whole offense gets bogged down at times. Tatum's numbers are likely down some lately but RWill is not playing well, Horford hasn't been consistent, and Smart lately, looks like a player who came back too early from injury. Plus I don't think the schemes are being executed overall as well (coaching).
Your point about the 3-point attempts though is a good one and something I want to add on to. I don't know what the foul percentage is for 3-pt shots vs. general 2-pt shots but clearly, you are going to get fouled more if you take it to the hoop. Kind of the difference between eFG% and TS%. And it is not just that, more fouls helps get you in the penalty quicker (leading to even more FTAs) and may get some players in foul trouble (force the opponent to take a player out).
The other thing with 3-pt shots is the long rebounds. The other team is kind of off and running many times off missed 3s more so than missed 2s. Again, I don't have exact stats but I bet the opposing teams scoring percentage after a missed 3 is higher than after a missed 2 (and there is a much higher percentage of misses with 3s).
So, as you suggest, there is more nuance to this than just the simple arithmetic equivalent that 33% from 3 is the same as 50% from 2.
