Starting with the Giants getting the ball back with just under 5 minutes left in the 3rd quarter (and them being down 17), the Giants had 3 TD drives the rest of the game totaling 8 minutes and 13 seconds of possession. I'm not sure you could say the prevent worked...the pick 6 to re-establish a 2 score lead when the Giants had the ball and a chance to take the lead is what really worked.
For ref the Giants had 2 other drives along with the 3 TD drives, one being the drive ended by the pick 6 obviously. Those 2 drives didn't even total 2 minutes.
