Rebounding/Undercutting

There's a difference in "boxing out" and what I call "backing out."

"Boxing out" is placing yourself between the basket and your opponent, and holding that position. "Backing out" is when you push your opponent or undercut him when he jumps for the rebound. "Backing out" is a foul, no matter what the coach may think.

Sounds like you made the correct call to me.

I certainly call it the way you do - making some allowance for the general Sumo-like pushing of both parties to the boxing out. I'm curious, however, about the rules basis you would advance when "undercutting" is what happens.
