Bill O'Brien will always remember his first Senior Day as head coach, that final time players race out of the tunnel in front of the home crowd, most of them knowing they'll never hear 90,000-plus fans cheering for them again.

O'Brien was moved last season by the emotion that hit the Penn State seniors as their names were called for one final game. And he's looking forward to witnessing that all over again.

"I remember the looks in their eyes," O'Brien said Tuesday. "They know this is the last time they're going to play on this field."

The seniors gave O'Brien and Happy Valley a win to remember in a tumultuous year: A rousing 24-21 win over Wisconsin that catapulted the Nittany Lions into the offseason.

This year, Nebraska is the opponent.
