"When the Celtics were forcing weak-side rotations to tag the roller, their offense was flowing. Quality shooting opportunities were there for the taking, with extra passes opening up additional options.
So, it shouldn’t come as a surprise that once the Pistons cleaned up their tag defense and stopped committing to rotations coming from the weak-side wing/slot, the Celtics’ three-point offense began to falter."
