Matt Ryan bought some time, scrambling to his left away from the Virginia Tech rush while searching for an open receiver.

He found just what he was looking for, fired a pass all the way across the field and kept No. 2 Boston College perfect.

Call it Ryan's Heisman moment.

The senior quarterback threw a 24-yard touchdown pass to Andre Callender with 11 seconds left and the Eagles validated themselves as national title contenders with an improbable 14-10 victory over No. 8 Virginia Tech on Thursday night.
