On Friday, the Celtics put forth their best defensive effort in a long time.
Jared Sullinger says it was about getting back to basics.
"We went back to training camp, brought some drills out from training camp and refreshed our memory on how we guard the basketball."
Part of the improved defense has to be credited to the return of Avery Bradley.
"His full court pressure wears down everybody," said Sullinger. "We need somebody like that. It's good to have him back."
