Block / Charge Situation

[jdw3018]

I'm more than willing to admit I'm wrong here - however, 4.23.3 deals with legal guarding position, and in the OP there certainly is no legal guarding position.

However, legal guarding position isn't required for all PC fouls. A player facing away from the dribbler doesn't have legal guarding position. But, if that player is stationary, A1 cannot displace him from his position on the court.

I'd contend that a stationary B1, even with a foot touching the end line, is still entitled to that spot. I'll also contend this is not a violation unless you deem B1 intentionally left the playing court.
