The atmosphere in Little Caesars Arena snapped without warning tonight as a routine possession during tonight’s NBA Cup game turned electric in an instant. The Detroit Pistons’ Cade Cunningham was called for a technical foul on the Orlando Magic’s Desmond Bane, but no one understood why. Fans saw the officials suddenly blow their whistles as players stepped towards each other, but the scuffle died down before anything major could happen. What happened between the two teams?

It began on a dead ball. Cunningham was walking over to his team’s side of the court when Desmond Bane shoulder-checked him, and the Pistons guard responded by shoving Bane back as officials rushed in. Detroit head coach JB Bickerstaff was heated, seen yelling at the officials in real time, for which, he was assessed a technical foul.

The frustration was palpable, but not unlike Bickerstaff, who has a reputation as an outspoken leader on the sideline, as well as someone not afraid to stand up for his players.
