was it a blown call?

[Ruben Trinidad]

Last night we had a 7th & 8th grader playoff, on overtime, team A is up by 2, 2 sec. left on the clock ball goes outbounce, team B's ball under there shooting basket, team B inbounds ball, player catches ball but fumbles it, finally he get control of the ball but the clock never starts, as the player passes to team mate they started the clock, keep in mind that about 3 seconds has passed by, that what my partner and I had, as player catches turns and shoots we blow our whistles and buzzer comes on, basket goes in, but we wave the basket off and called it a game. Player made the basket before the buzzer went off but that was because the clock was started late.
