Fouls - 3 questions

[BktBallRef]

I don't see the difference in this and backing out. Just because the player is moving to the side is of no consequence. He's still blocking and riding the opponent out of the play. Have I called this a foul? Sure I have. Have I not called it a foul? Sure I have. It all goes to adv./disadv. Like I said, it may or may not be a foul, but you can't discount that it's possible. 1, 2, 3 seconds doesn't have anything to do with it. That's plenty of time to commit a foul. JMO
