The Celtics took Monday off, presumably to recover from the stunning news of Rajon Rondo’s season-ending knee injury and to formulate a new plan.

Team president of basketball operations Danny Ainge said the Celtics will not make a knee-jerk reaction to losing their starting point guard. While the national media actively discussed whether the team should start fresh by dealing Paul Pierce and Kevin Garnett and rebuild through the draft and free agency, Ainge said the organization will take a deep breath, assess its options, and determine whether another point guard is needed.
