rainmaker, your exactly right. I agree. I think you just stated my words differently (maybe clearer).

In NFHS there is a casebook play which states that it is not a foul to be lying on the floor and be tripped over. I was stunned to see the NCAA ruling that was posted in this thread. I would not call a blocking foul on someone lying on the floor. Also, if the player who rebounded the ball and fell on top of another player, who was already on the floor, never touches the floor with anything but a hand or foot, I don't even have a traveling violation. Just play on.

The "anything but a hand or foot" is a FED rule.

It's traveling in NCAA if (a) the pivot foot moves or (b) the player "falls to the court." Merely touching the floor with the, say, knee is not traveling if the pivot foot doesn't move.
