It's easy to think offense with superstars Russell Westbrook, Paul George and Kyrie Irving on the court. But Oklahoma City and Boston also are strong defensively.

The Thunder give up the 12th fewest points in the league. The Celtics rank No. 3 in scoring defense and No. 2 in defensive field goal percentage.

The Celtics are giving up just 100.6 points per game in their last six games discounting a 115-point performance that Golden State put up against Boston.

There were just 196 points scored during the first meeting, which the Celtics won, 101-95, back in late October. It was the fourth time in the last five in the series that the Under has cashed.

Note this is a day game. That's usually a plus for an Under, too.
