Block/PC + Positioning (video)

I think I'm leaving the first part alone. The dribbler doesn't appear to extend an arm to push, and the defender only moves as much as he does because he's so much smaller... not because he was pushed hard. I see too often where a foul is called on somebody just because they are bigger and going against a smaller player who falls.

I agree that the second is a PC foul, as I see the defender gain LGP against the second dribbler before getting pushed to the floor.
