NEW YORK – Detroit coach Monty Williams has slammed National Basketball Association (NBA) referees for making the “worst call of the season” after the Pistons slumped to an agonising last-gasp 113-111 defeat by the New York Knicks on Feb 26.

A thrilling clash at Madison Square Garden swung decisively in favour of the Knicks in the closing seconds, when officials failed to penalise New York’s Donte DiVincenzo for a blatant foul on Pistons forward Ausar Thompson as the two tussled for a loose ball with Detroit leading 111-110.
