These are now some uncharted waters for the Spurs with HC Gregg Popovich sidelined, and assistant Mitch Johnson now pulling the strings from the bench until further notice. San Antonio's offense, in particular, has labored in recent games, especially last night vs. the Rockets when guilty of a ghastly 19 turnovers that contributed greatly to the lo[sided 127-120 loss. In Monday's loss vs. the Clippers, the Spurs hit only 11 of 41 from beyond the arc in another inefficient display. The offense has some very pedestrian numbers, scoring at only 104 ppg, hitting 44.9% from the floor,. and 32.1% beyond the arc. Meanwhile, Portland has been trending "under" for the past week-plus, landing that way in four of its past five games. Play Spurs-Blazers "Under"
