Detroit Pistons coach Monty Williams criticized officials for what he said was the “absolute worst call of the season” in the final seconds of a loss to New York. He was right: There should have been a foul called. That’s what the referees determined after watching the replay of Ausur Thompson’s collision with Donte DiVincenzo along the sideline. Crew chief James Williams says DiVincenzo should have been whistled for a loose-ball foul on the play. After Thompson lost the ball, the Knicks made the winning basket with 2.8 seconds left.
