Boston's lineup is fully intact headlined by Jayson Tatum and Paul George, while Chicago is without starting center Nic Claxton (hamstring, out until Nov 4) and has both Patrick Williams and Noa Essengue listed as questionable with separate injuries — leaving the Bulls undermanned in the frontcourt. The Celtics are averaging 123.8 projected points to Chicago's 109.8, a 14-point gap that aligns almost exactly with the spread, and a hobbled, thin Bulls roster traveling to TD Garden gives Boston every structural advantage needed to cover this number at home.
