System matters. He's shooting less from 10-23ft and working more off of cuts than iso like he was in NY (assists on his FG's are up 20%).
Now, he's obviously on a heater. Which is awesome, but eventually the 3pt shooting will calm the fuck down. Working as a cutter though with all of the playmakers we have (everyone else in the starting lineup passes the ball better than average for their position) should be a durable change to his shot selection.
