Boswell's decision making has improved considerably over the season. His defense has similarly improved. He still has trouble against the quick first step.
My concern is that the offense struggles when he is the lead PG. Teams can go under screens and pack the lane. The result seems to be we pass the ball around the edge, make a whole lot of aborted drives into a packed lane (often resulting in a turnover), and then settle for a poor, often contested, 3 late in the shot clock. If Kylan could get back to reliably shooting 35%+ from 3, he might be a serviceable lead PG. With his current shooting, I don't think he can be more than a secondary ball handler. The pairing with KJ is boosting Boswell's results. KJ breaks down the defense, and then Boswell's passing and 2-pt game works.
