Bill Sy: One of the tenants of the Celtics’ versatile defense is that they rarely double team. It doesn’t matter if it’s a smaller player guarding a big in the post or a big going one-on-one with a quick ballhandler on the perimeter. They’ll switch on almost any action and invite players to beat them individually.
However, sometimes they do. It almost seems like Brad Stevens decides to do it at random to keep opposing offenses guessing. I remember last season in a game against the Magic, the Celtics double teamed Nikola Vucevic on the catch.
