What makes me think 1200 attempts is a lot of attempts? The fact that just is clearly is. 250 made threes is the minimum for being on the NBA career 3P% list. Duncan already had 520 made threes from those 1200 attempts. 1200 attempts is a very big sample size. Is there any player in history whose 3P% over a 1200 attempt sample size ended up being a big outlier compared to the rest of his career, i.e. he ended up being much worse? That's my point.
 
Well statistically, Duncan Robinson himself hasn't maintained his insane efficiency of 44% from his breakout year and has lost a significant chunk every year since.  I remember this debate back in the old apbr forum about just when exactly do we know a guys shooting skill enough to model into team projections. I don't remember what the consensus was, so I was hoping you could expand on the "it just is", reminds me of Tod Howard boasting "it just works". 
He's obviously a great shooter and his gravity is well known but there are levels to this.  Put it this way, do you think he'll ever again touch that elite 122 ortg  from that magical season?
 
I figured that 250 made threes being the minimum to qualify for the CAREER 3P% leaders, and we're talking a sample size of more than double that (520 made / 1200 attempts), would be enough right there. 1200 attempts. I mean I didn't think I needed to go super into depth about why that is a **** ton of attempts and a big sample size. 
I think the 42.7% he shot over those 1200 attempts is likely a good indication of the shooter he is. That's all my point is. Might he really only be a 40-41% shooter? Possibly. But almost definitely not the 37% he is this season. Would love to know if there is any shooter who had a decline like that over the rest of his career. Something like:
42% over first 1000+ attempts, then
37% over next 2000+ attempts
Or 40% to 35%, anything like that. But that's probably never happened and probably never will, because 1200 attempts is a huge sample size.
