The NBA Totals play is on the under in the Houston at San Antonio game. Rotation numbers 507/508 at 8:05 eastern. This game fits a perfect totals system that plays to the under for division home teams with rest and a total of 200 or higher if they lost to the spread by 7 or more points as a road dog and scored 90 or more points, vs an opponent that scored 110 or more as a road in their last game. The Spurs are 4-0 under at home after allowing 120 or more on the road and 5 of 6 to the under home off a road spread loss by 21+ points. As a favorite from -9.5 to -12 they are 5-1 to the under. Look for the Spurs to tighten the D after getting rolled by Golden St. Take the under.
