Nobody Moves for Rebound After Missed FT

[inigo montoya]

Partner calls a common foul on B1 and it is B's 7th team foul of the 2nd half. I move to Lead to administer free throws and announce verbally and visually that we have "one and one" and bounce ball to free thrower A1. A1 misses his first free throw, and nobody moves from their lane spaces. Ball bounces right into the chest of rebounder B2 (who is occupying the first lane space) and he catches it. Still nobody moves. Before B2 tosses the ball back to me or travels with it, I whistle the play dead.

My partner looks at me like I have two heads for blowing the whistle.

I thought that if nobody moves for the rebound (or if only one team), we go to AP and resume with a throw-in out of bounds. He said "no, just give it to red [B]." He also has a few more decades of experience, and he was convinced he was right while I was maybe 95% sure. B had the arrow anyway, but we did not reverse the arrow on throw in. B lost by 25 so I'm not losing sleep, but I am having trouble finding the case play. So how badly did I kick this one?
