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."
Kurt Rawlings threw for 177 yards and a touchdown to lead Yale over rival Harvard 24-3 on Saturday at Yale Bowl in New Haven, Conn., securing the Bulldogs' first outright Ivy League championship in 37 years.
Yale beat its rival for the second year in a row, this time capping a 9-1 season (6-1 in the Ivy League) and running its all-time record in the series known as "The Game" to 67-59-8. It's the first time the Bulldogs have won two in a row in the rivalry since a three-year winning streak from 1998-2000. Yale went 3-7 last season.
Yale's defense held Harvard (5-5, 3-4 Ivy) to 164 total yards, sacked Harvard QB Jake Smith six times and forced four Crimson turnovers, including a fumble that was returned 19 yards for a touchdown by the Bulldogs' Malcolm Dixon.
