The Spurs are a team that can stay with the NBA’s elite teams when they’re playing well, but they always have lapses of a few minutes, often at the ends of quarters. Tonight, it was one of those lapses, as they lost composure at the end of the third quarter and let the Nets go off on a 6-0 run to go into the fourth quarter with a lead that ended up costing them control of the contest. The Nets turned on the heat in the final frame, and put the game out of reach with Kyrie Irving and James Harden putting the Spurs away despite good performances from Dejounte Murray with his ninth triple-double of the season, and Derrick White, who sacrificed his body to keep the Spurs in the game.
