Quinn Cook and Austin Rivers sat down with the Warriors sideline reporter and they got to discussing Coach K. While his love of Beyonce surely is not news around these parts (it was to Kerith Burke), I have never heard the story Quinn tells her about Coach K using Beyonce to motivate the team. Also, there's more recognition that Coach K is a seriously funny dude, which is a drum I'll never stop beating!
There's a video clip, audio clip, and text
here.
EDIT: I realized after submitting that the title is worded such that it sounds like Coach K told a story about Beyonce. That's not right. It's probably more accurate to say a "... Great Coach K Story Involving Beyonce."
