It's been a frustrating afternoon for DeMar DeRozan. He missed his first six shots, and his Raptors are losing ground to the Phoenix Suns in a very important Sunday afternoon game.
Thus, he did what many struggling players do: he attacked the basket with little regard for his teammates. And when he inevitably was stripped, he got angry because he thought he was fouled.
That's all the context you need for this.
DeRozan was T'd up for his efforts, but that's impeccable timing on the redirect.
