Chris Mannix joins Adam Kaufman and Evan Valenti on Celtics Beat to talk about the Celtics win streak and defensive issues. The Celtics are on a four game win streak, but Mannix thinks their defense could be an issue. Boston is 16th in the league in defensive rating (111.7), but their offense has been solid. Their four wins in a row is tied for the longest win streak in the NBA. Mannix thinks this could be the turning point for the C’s, but Jayson Tatum and Jaylen Brown need more help.
