By calling the T, the defense (with no time outs remaining) benefits greatly. As happened here, even with the free throws being made, it was able to steal the ball and attempt a 3-point shot. Let the defense grab the ball. Just don't blow the whistle. Let time expire.

I agree with you in practice, but the interpretation says otherwise. There is a difference between interfering with ball and interfering with the thrower.

… B1 reaches through the boundary plane and knocks the ball out of A1's hands.
