Is this a do over?

[rbruno]

Team A scores and is down by 1 point at the end of the game. Team B calls time with 3 secs on the clock. The ball is inbounded in the backcourt but the timer fails to start the clock. Team B coach is screaming that the clock did not start. The officials blow it dead. The trail tells the new lead that he reached two on his backcourt count before the whistle blew everything dead. They decide to replay the throw in with 3 seconds on the clock. Is this the correct way to handle this? Could they have used the trail's count and put one second on the clock and inbound where the POI was on the whistle?
