Foul in the last second

[NoFussRef]

Last few seconds of OT, tie game. Team A gets it in and as A1 attempts the mid-court hail-mary to win B1 nails him. I call the foul and B-Coach almost has an aneurysm. A1 goes to the line for 3 free-throws with .2 seconds on the clock. B-coach ices him with timeouts in between each shot but he still sinks 2 of 3. On the inbound B gets it in and time expires. A wins.

B-Coach says to me "HOW DO YOU CALL THAT FOUL???"

(Not how could you call that a foul?, not how is that a shooting foul?)

He wasn't questioning the foul itself, just why I would call it!!! I guess he felt officials should allow a game to go into another OT rather than call em as we see em. I gave him the "Foul in the 1st minute is a foul in the last minute" speech and when he groaned I followed up with "You said it yourself. How could I call that "FOUL".

(meanwhile I am wondering what B1 was doing anywhere NEAR A1 in that sitch!)
