Double Violation

[co2ice]

The ball does not become dead immediately if B enters the lane before the ball hits the rim. But it does if A enters the lane too soon, ruling is to disregard the throw and go to the next one. If that throw is once again violated by both teams then A entering the lane caused the ball to become dead immediatley so its a violation on A and B gets the oob. You would'nt go to the arrow here because its a simple lane violation.
