The NBA Power System play is on San Antonio at 8:30 eastern. The Spurs are in a perfect League wide system. Play on favorites with no rest off a home dog loss vs an opponent off a home dog win that scored 110 or more. The Rockets are off the upset win over Cleveland and have failed to cover 4 of 5 on Fridays. The Spurs lot at home to Miami last night but have covered 4 of 5 vs losing teams. Look for the Spurs to cover.
