Danny is doing more with the ball now than he has in the past. He's not spotting up nearly as much. When he does, there aren't other threats on the floor to shoot the 3 like in days past so all the perimeter defense can stay at home on Danny. When Marco was out there, it was a "pick your poison" thing, not now. They'll leave Tony wide open to brick a 3, and Patty has to curl off high screens to get his, but Danny is a spot up shooter who's lately been watching too much Curry because he's spotting up several feet from the 3pt line. He cannot rely on Kawhi to shoot the 3 and draw defense because KL would rather put the ball on the floor. Danny cannot put the ball on the floor with any success so he's stuck with that shot or a pass, so they close out hard on him and he either takes a bad look or no look.
We aren't running the same sets as we were, and LMA in the post is still 12' out and a much better option than the risky pass cross court to Green. So then Danny's shots often come cold or in transition or simply after more movement than he's used in the past. He's not the savior of the Spurs on offense, but we need his defense. We aren't the 3pt threat we were in the past but we seem to be doing ok.
