Porzingis has felt refreshed after Carlisle’s resignation, team sources said. Kidd has made a point of giving Porzingis the green light to take the kind of shots Carlisle wanted to eliminate from his arsenal. Porzingis’ overall offensive numbers are similar to last season — he has been more effective on post-ups but has slumped from 3-point range — but he’s noticeably happier. His chemistry with Doncic has improved, as both were eager to start the new season, part of the better “vibe” several Mavs have cited under Kidd.
