Granting a timeout

[Toren]

Let me set the table:
Playoff game 29.2 seconds left in the game, 58-58 is the score, boys 3 man-mechanics.

Team A has been granted a timeout. I'm the C. The ball is at Team A's disposal opposite sideline from the benches.

I have eyes on players and am close to coach because the place is packed and I want to make sure I hear a timeout call. He's at most a step away.

The T bounces ball to Player A1 to begin the throw in. He starts his count. tweet tweet, 5 seconds. "Timeout" coach says...my first instinct is tweet, which I do, but nobody can hear as I was already certain my partner's loud tweet came first.

I turn to the coach and say, my partners whistle came before your timeout coach. He says "how, I'm standing right here next to you". I say, his whistle came first. He says "I understand"

After the game, I talk to my partners and they both said, they would have granted the timeout even if they heard the whistle first.

What say everyone?

This is my first playoff experience. Great game.
