Chicago and Boston were first in defensive efficiency this season, and the principles in each system are the same because the architect is the same current Bulls coach and former Celtics assistant Tom Thibodeau. The Heat struggled mightily against such defenses in the regular season, going a combined 1-6 against the Celtics and Bulls largely because Wade and Bosh were taken out of their game. It's a difficult defense for Wade and James to play against because it punishes ball-stoppers so much. Both teams will load up against the strong side and force teams to drive and kick and reverse the ball.
