Tee,I checked out the NCAA rules on line. The URL is below. Click on "basketball rules" (it's a PDF file) and read Rule 6-3-1AR4. That basically says that they HAVE to call the double foul,and then go to the AP and reset the shot clock.There's also a clock reset whether the foul on the offensive player is called a charge(without the ball) or a player control foul(with the ball).I don't have a clue what they could be looking at on the replay,unless a made basket was involved.I'm guessing, but this may be it.
