In a crucial Game 7 matchup against the 76ers, the Celtics will start Derrick White, Jaylen Brown, Ron Harper Jr., Baylor Scheierman, and Luka Garza. Jayson Tatum’s absence due to a knee injury has led to lineup adjustments, including the inclusion of Harper Jr. and Garza, while Sam Hauser and Neemias Queta will come off the bench. Coach’s decision to shake up the starting lineup underscores the need to find a competitive edge in Tatum’s absence.
