Backcourt on throw-in
 

A1 throw-in from frontcourt base-line. B1 deflects throw-in in f/c followed by A2, with f/c status, deflecting ball which then goes into backcourt. Can Team A retrieve the ball in the backcourt? Is there a difference between NCAA or NFHS since in NCAA there is team control on a throw-in?

I know that in both rule sets that if B1 deflects the throw-in A2 cannot jump from the f/c, catch the ball in the air, then land in the b/c because the throw-in ended when B1 deflected the ball and thus the b/c exemption would no longer apply.

No violation as team control was not established until after the ball made it to the backcourt.

You are correct that there is team control during a throw-in in NCAA (dumb rule), but there are exceptions in place so that your play is legal. (NCAA 4-3-5 and 4-3-6)

I can see that for NFHS. But in NCAA there is team control. And B1 deflecting the ball ends the throw-in. So I guess I'm more wondering if this would be a b/c violation in NCAA.

I had a similar play last night in a HS spring league. A1 has a FC endline throw-in deflected into the BC by A3 then A3 runs to pick up the ball... I had nothing, well except a new 10 second count :D (much to the surprise of my 2 veteran partners). At the next TO my reply was simply "although the throw-in ended on the deflection, there is no team control on a throw-in, TC began when A3 possessed the ball".

I believe the same holds true in your sitch.

Not sure about NCAA...

No violation in NCAA

Thank you Bob for all your hard work.
