San Antonio has been one of the top defensive teams since the All-Star break. The Spurs have held nine of their past 12 opponents to 105 or fewer points. The Under is 10-2 in San Antonio's last 12 games. 

The Spurs, though, are in stop-the-pain mode having dropped two in a row. 

Boston is in worse shape. The Celtics have dropped three in a row with the third one coming in unbelievable fashion on Saturday night. The Celtics blew an 18-point fourth quarter lead in a 124-117 road loss to Charlotte. The Celtics scored five points during the final 8:21. 

Brad Stevens called out his team's lack of toughness following that Boston loss. The Celtics return home now for this matchup. You have to believe the Celtics are going to play intense defense. 

Boston could get back injured center Aron Baynes. That would be a plus for the Under as Baynes offers toughness underneath but little offense. There's a possibility, too, Boston could be minus Jayson Tatum, its second-leading scorer. Tatum suffered a bruised lower back against the Hornets.
