1. The Celtics defense got after the Suns right from the jump. As expected, Devin Booker was the focal point for the defense, but not how you might have expected. Boston opened with Jayson Tatum guarding Booker, not Marcus Smart. In part, this was because Brad Stevens decided to trap Booker whenever possible to force the ball out of his hands. This allowed Smart to roam and switch off the ball. The strategy worked, as Booker only attempted 13 field goal attempts and was held below his average with “only” 20 points.
