New coaches bring change — that’s often why they’re hired. Ime Udoka has started with some big tweaks on the defensive end. Mainly, emphasizing switching on a higher degree than before.
In theory, the Celtics have the right personnel to be very switch-heavy. Jayson Tatum, Jaylen Brown, Marcus Smart, Josh Richardson and Grant Williams are all multi-positional defenders. Al Horford is a master of angles and Robert Williams is quick enough to keep others in front.
In practice, getting comfortable in a new system with such an unorthodox form of defense means bumps in the road.
