Depends on the amount of contact IMO. I had one yesterday like that on a box-out. The 'boxer' moved the opponent half-way across the lane, then fell down because he was off balance from the overextension of his screen. I called a foul on the screener because he moved the other guy so far. He wasn't just holding his ground, he really moved the guy who was trying to get to the ball. The coach complained because his guy ended up on the floor. Obviously, the coach never saw HOW he got on the floor. I said coach, "He moved him 5-feet." I guess if you end up on the floor, you were fouled, huh.
