I think this is the point that you are making that people aren't getting. Correct me if I'm wrong but throughout the game if Nurk finds himself wide open from three, you're cool with him taking the shot but you don't want him taking contested threes and you definitely don't want him taking threes with the game on the line. Also, if you're like me, you don't want him living out there which would take time away from him dominating the paint like he is capable of and should be worrying about more than shooting outside.
I want Nurk to take 3-5 threes per game as long as they come naturally from him setting outside screens and getting left wide open. I don't want us running plays to get Nurk screens and I don't want him being seen as a go to outside shooter. I also don't want this to distract Nurk from the things he needs to be concentrating on the most which are dominating the paint on both ends along with going up strong with the ball in the restricted area on offense. That being said, teams getting punished for leaving Nurk alone beyond the arc and not being able to use simple drop coverages against us does open up driving lanes for all of our guys that need them and that happens to be the entire roster.
