New free throw alignment and 1!

[MOFFICIAL]

I don't have access to my books right now-the new alignment calls for a maximum of four defensive and two offensive players along the lane lines. If an offensive player opts not to line up can the defensive player position himself in his spot? NF and NCAA Men's please

Second question.
I was watching a game (rec league NF rules) the other day and the tapper after tapping caught the tap before it touched the floor or another player. He passed the ball immedietely without dribbling. I questioned the official and he said as long as he didn't dribble it was a legal act-again I don't have access of my books. NF please
