Lauri absolutely has to become quicker making the reads before the help defense comes. To move the ball or put the shoulder down and go to basket. His stance and handle are also way too high too often so it's really ugly in the paint.
He's now the clear target and playing with the worst backcourt of his career, so if he doesn't want his splits to plummet badly, he needs to get better in the paint. At this point I've given up my unrealistic hope of another jump to become an clear cut all nba (still might do it once or twice, if stars will be aligned). There's too much work to do with his on ball actions.
