Bizarre. I guess they can call a technical whether I agree or not. She reviews the play and there's no way whatever she saw that deemed a technical occurred before the game clock expired. As far as I know, you can not alter the score of a completed game (time expired) for anything that happened outside of the game itself....EXCEPT, a score keeping error. But, that error would have occurred during the game.
What you are missing is that it is not a "completed game" at that point, i.e. when time has expired. According to the rules, the game is over "when all officials leave the visual confines of the playing area at the end of the game."
What a pandora's box. A technical on the home team could be called when kids instantly rush the floor after a close win, especially where the home team has been warned during the game for having fans throw something onto the floor which happens often. Any end of game words between teams. "A game is never over til it's over" apparently extends beyond the final horn, who knew.
Sometimes refs run off the court for safety and we're saying the game isn't actually over and they can call something until they sign a scorebook later? If that's true it's absurd. A coach gets on an official for a technical called against him during the game, and can pick up another after the horn? Even if they administer the game until a final act with their signature, their authority must be limited?
They wouldn't call a technical for a crowd storming the court after the buzzer because what is illegal is fans "preventing the ball from being promptly made live or by preventing continuous play." If the clock had expired, the crowd wouldn't be preventing play.
And no, we are not "saying the game isn't actually over and they can call something until they sign a scorebook later". According to the rules, "When all officials leave the visual confines of the playing area at the end of the game, the officials’ jurisdiction has ended and the score has been approved." There is no requirement that they sign the scorebook at any point.
One other point that a few other posts have referenced is when the authority of the officials starts and ends. The NCAA rule says:
. "The officials shall have the power to make decisions for infractions of rules committed either within or outside the boundary lines from 15 minutes before the scheduled starting time of the game through the referee’s approval of the final score."
