These Spurs don’t quit. Somehow, someway, they have now won their third game in a row after a 1-16 stretch of play, this time against the much-improved Cleveland Cavaliers. After dominating most of the first three quarters to get out to a 19-point lead, the young Spurs did what they are prone to do against better teams and started falling apart in the fourth. The Cavs mounted a furious comeback and got within a point with a chance to win it at the buzzer, but they missed on two good chances, and the Spurs held on for the 112-111 win.
