The Cavaliers got a bit of a favorable road whistle.

Many believe that a loose-ball foul should have been assessed on Allen, which would have led to free throws for Thompson that could have potentially sealed the game for Detroit. Instead, the Cavaliers used their fourth-quarter momentum to down Detroit in overtime, 117-113 , to take a 3-2 series lead in the Eastern Conference semifinals.
