What would you do?

I ended up passing on the INT, and allowed the A player to continue for the layup. I thought the easy 2 points was a better strategy for them. I would have not known that A was going to be fouled on the shot. I think he made 1 of the 2 foul shots and team A ended up winning.

After he was fouled on the shot, I see no way to have called the INT, because a couple of seconds has passed. Too late in my game... I gotta make that decision to call it or not call it, especially at the end of a close game, when 2 seconds will count.

I told the coach after that I made that decision based on my experience in basketball.
