Wild Throw-in vs. Pressure

[CMHCoachNRef]

Rather strange situation happened in a game last year. We were back at the same gym on Friday night and I brought up the play. Three officials, three different views of the same play. Ask a different crew on Saturday and got similar results.

Here is the situation: Team A scores a basket with 0:05 seconds left in the first half. Team A is running a Diamond Fullcourt press. A5 is aggressively defending along the endline. B1 is preparing to inbound the ball. This particular high school gym has very little room beyond the end line (about 3 feet between the end line and a brick wall (there is no restraining line). B1 decides to run the end line. B1 stops, sees a teammate near the division line. B1 attempts to make a baseball pass. As he reaches back to throw the pass, his hand/the ball contacts the wall. The ball goes directly into the hands of A5 who puts the ball into the basket. What, if anything, do you have?

Basket, throw-in violation, reset/redo due to the proximity of the wall???
