Delay of game question

[letemplay]

Team B has not had a delay warning yet and down by 3 with about 10 secs left and out of time outs, scores 2 pt goal. B5 grabs ball before A can get it, possibly hoping for delay whistle which stops clock in their favor. Officials are reluctant to hit whistle for this reason, possibly, I don't know, but no stoppage occurred. B gets to set up press and almost gets steal before A controls and advances until final horn.
