The money has been on the Under as it opened 0.5 @ -120 before it was bet down to 0.5 @ -125.
FACTORS THAT FAVOR THE OVER:
The San Antonio Spurs will likely see a rise in possessions today from being pitted against the 5th-quickest pace visiting offense in the league over the last 10 games (the Rockets).
