Interesting. So it seems like the flynig V formation (from the might Ducks

with a V of teammates blocking for the ball handler would be legal as long as they are moving forward in a straight lin, but not backwards or sideways?
Seems to me more like if the dribbler is moving in such a way that he uses his moving (forward and in a straight line) teammate as a screen and the defender runs into him then the foul would have to be on the offensive player.
