Celtics at Spurs picks and predictionsPrediction

Spurs 113, Celtics 109

The SPURS (-155) are worth a look as moderate favorites, as they’re not priced out of line. If you’re a bit on the conservative side, and you just want to declare a winner without worrying about the points, San Antonio is a solid play on its home floor.

If you’re a more traditional bettor, backing SPURS -3.5 (-105) is a much better play.

The Celtics have been hot lately, but with the exception of the Cleveland game, they haven’t really had much success against top teams lately. So, while Boston’s 5-1 ATS run is nice, it’s not overly impressive. Back San Antonio in his marquee matchup.

UNDER 222.5 (-110) is the lean, but go with a half-unit play at most.

The Under has cashed in 5 in a row for Boston, and 8 of the past 9 outings. While the Spurs have hit high in the past 2, the Under has a 5-3 edge in the previous 8 contests. Let’s go low, but don’t get crazy.
