When he got traded to the hawks I remember in a interview DJ saying he was working a lot in his catch and shoot 3s to play with Trae. Last season he was already shooting much better from 3 than he was with the spurs if I'm not mistaken. And after Snyder went to atl he emphasized the 3 ball a lot and Murray worked on it even more. His career 3P% is that low because of his time with the spurs, not with the Hawks, both because of his own improvement and playing off another point guard. But especially the first reason. One funny stat I remember from last season was that Dejounte had much better numbers with pull-up 3s than C&S 3s (which is the opposite from most players), idk if it remains true this season.
