[just another ref]

I actually had a play like this earlier this year. Man to man defense. Point guard beats his man and takes off just inside the free throw line. This kid had some serious hang time. But another defender was standing in the lane guarding his man the whole time, more or less facing the sideline. He looked up and saw the point guard coming at him and kind of shrunk away from the contact. Point guard's knee hit him probably in the upper kidney area, and they both crashed to the ground. Easy PC call. Coach screamed, "No, that can't be on my man! He's gotta square up to take the charge!"
