TriggerMN has this correct!
Not a violation, just a ball OOB. A1 failed to successfully inbound the ball to a teammate when they had endline priviledge. Do not penalize B for good defense.
Here is another way to process this:
A1 attempts the throw-in. B1 slaps the ball back OOB and A1 catches it while standing OOB. Do you give it to A1 for the next throw-in? No, because B1 did NOT commit a violation, just great defense.
In this case the ball would actually be awarded to B.
