[JAdams]

I actually had a similar sitch occur several years ago in a JV game. A1, on defense at the beginning of the second half, rebounded B1's shot, then apparently forgot which basket was his. A1 put up a "shot" at the wrong basket, and was fouled by B1 as he "shot." The ball went in the basket. Although my partner and I kicked the call, we looked it up after the game, and here's what we should have called.

Because A1 "shot" at the wrong basket, it is officially not a try. Because it wasn't a try, the foul by B1 wasn't in the act of shooting, and therefore, should have stopped the play immediately. Assess the foul to B1, wipe off any points, and give the ball to A1 out of bounds since it was a common foul.
