Losing the lead midway through the 4th the way they did (i.e., a Pick-6 right after they had just retaken the lead with an offensive TD and then stopped Purdue on their ensuing possession) was a huge momentum shift and really brought the Purdue crowd into the game. But PSU's defense, which had already shut down Purdue on their first 2 possessions of the 4th, continued to stand tall in the face of bigtime adversity.... and then Cliff delivered on the "must have" possession to give PSU the lead again.... You just can't understate how huge that drive was for the team's and Cliff's confidence on a go forward basis.
