Come on. Tucker is a defensive moving screen waiting to happen. He does nothing but run into guys like that all game long. I'm not sure he does anything else but run into people and pretend it's not to disrupt offensive movement off the ball. The Celtics main problem on offense (aside from missing everything) is lack of movement off the ball, and the 76ers are clearly intentionally disrupting it. Embiid does it too, impeding offensive players as they move without the ball. He mostly sticks his legs out in a wide stance to do it. In hockey it's "interference".
Celtics were awful, deserved the loss, but that was no flop. That was PJ wrecking a guy cutting across the lane to disrupt the motion. It's Doc's whole defensive strategy and it's working. White and Brown have been knocked down or hip checked a bunch of times the same way. It keeps resulting in these bad ISO drives into traffic. Credit to Doc, Joe needs to find out how to counter it.
