I don't believe for a second that she was close enough and/or the arena was quiet enough (between cheering, booing, and all of the obnoxious stuff during timeouts and stoppage between quarters during the most anticipated home game of the season) for her to hear that. Sorry. It's not like they're chatting loudly on the baseline while the building is hushed and no one else besides her heard it unless she, again, has the best hearing on the face of the earth. But maybe it happened, I don't buy it, though. I would imagine if she heard it, that several people in the crowd would've heard it, too.
But I've voiced my dissent and am taking it for what it's worth.
