YouTube - Louisville cheerleader almost costs them the game
There is the video for everyone to see. If you watch the video around :18 seconds you will see the clock is down .3, and then the cheerleader jumps for joy and grabs the ball and tossed it in the air before the old L --> new T, blows his whistle.
They went back and looked at the monitor to determind how much time was left after the ball went through the basket at .5. That is where it should have stopped and played should have resumed from there except for the bonehead T for the cheerleader.
I hope this helps everyone.
