Player that is on the floor

[BktBallRef]

I addressed your other concerns, except that I didn't point out for you that both the rule and the case play state, "...every player is entitled to a spot on the playing court..." I figured you could read that for yourself.

The fact that it's addressed in the case play acknowledges that it's in the rule and applies to situations where a player ends up on the floor and did not get there illegally.
