This is the play on which Paul Pierce fouled out. It happens right at the beginning of the clip, at the other side of the lane.
I think the best part is… I'm not sure Pachulia even realized he drew the foul.
Horrible… horrible call. I'm willing to bet that happens on every play in the NBA. That, to me, was such a non-call… it makes me think they were looking for a reason to call something on Pierce.
