I was curious about a few things.

1) On an OOB throw in if the in-bounder steps onto the court before releasing the ball is this a violation or does the in-bounder have to step completely over the line?

2) Can a time-out be requested by a player in the air falling out of bounds or into the backcourt?

3) My understanding: A player can pivot after a jump if they gathered the ball mid-air but if the player gathered the ball prior to jumping they may not use a pivot after the completion of the jump stop?

4) Traveling related again: How far does a player actually have to roll over with possession of the ball to be considered a travel. I've seen players in college roll over and call a timeout with possession.

5) Does the closely guarded count continue if ANY defender is within 6 ft of the offensive player with the ball.
-Meaning if defender A is closely guarding offensive player A while the closely guarded count is at 3 seconds and then defender B switches over to offensive player A while defender A is no longer closely guarding the offensive player.
