A1 is not dribbling the ball...dribbing is "ball movement"
A1 is not holding the ball...therefore no travel.
It is not an interrupted dribble as it hasn't gotten away from A1
B1 hasn't earned a held ball
I agree with 1, 3, and 4. Still, if A1 pinned the ball against A2's leg, and both took steps, was it not established that we would have a travel, even though A1 still would not be holding the ball?
