The Celtics have made 3.9 fewer threes per game during their last seven matches than they did in their first 26 contests.

Phoenix Suns News

Confirmed Lineup: Chris Paul, Devin Booker, Mikal Bridges, Torrey Craig, Deandre Ayton

• Devin Booker (groin) — In

• Cam Payne (foot) — Out

There should be reduced offensive opportunities available across the lineup due to Booker's expected return, and Landry Shamet's role should be reduced most sharply.
