Lessen 3PAs: The Suns, Bulls, Sixers, Grizzles, and Cavs are in the bottom third in 3PA per game, which means that teams can sustain winning while attempting less threes.
The Smart-Brown-Tatum-Horford-Williams III lineup is 3rd in EFG% and TS% so there are ways around it. A less static offense, 3PA attempts, and ball sticking, and a more dynamic offense transition, cutting, passing, and shots at the rim can make it work.
The Celtics brass must be dedicated to changing the offensive culture because White embodies the dynamic offense qualities mentioned + Theis setting picks, shooting, or passing immediately. They’ve assembled a cast of low usage players to surround the Jays.
