I have question I am hoping a ref or someone can answer. I am teaching my youth team the SU flip offense(or trying to) and I saw ion USlacrosse mag Instagram the SU v FL highlight. I saw where the flip person flipped the ball to the her teammate then backed into the defender to block her from staying on the girl she flipped to. Is this legal? I would love to add that in, but thought it would be called for interference or blind pick. Any insight is greatly appreciated.
