Exactly, Carnac.... it seems we wouldn't need to go any further than to ask Nika and Amari for their thoughts on the matter. Clearly, in the game in question above, Amari instinctively felt to pick the ball up and hand it to the ref was the respectful and courteous thing to do.
I would admire Nika that much more if she had done that, and hope she will in the future, maybe after the Huskies have beaten Stanford or SC in the national championship game? Dribbling the ball for another three or four seconds would hardly lessen the joy of a post-game celebration.
