The 108,000 Penn State fans that stuffed Beaver Stadium left with memories that will live on for years.

There was Bill Belton’s 3-yard dive on fourth-and-1 that kept alive the winning drive in the fourth overtime. And his 2-yard scamper that helped the Nittany Lions upset then-No. 18 Michigan, 43-40.

Or how about Christian Hackenberg’s 29-yard completion to Brandon Felder on the tying drive in regulation?

But no play stood out like Hackenberg’s toss to a leaping Allen Robinson in the corner that sent the wide receiver crashing down a yard from the goal line. Hackenberg sneaked in for the first rushing TD against Michigan this season, tying the game at 34-all.

Of all the thrillers, which one is stamped in coach Bill O’Brien’s memory bank?

“I don’t know,” he said Tuesday. “I’d have to really probably have to wait until the end of the year because really, our staff, our players, we’ve moved on.”

Like most coaches, O’Brien is always on to next game, even as fans and players are still basking in perhaps the program’s signature win of the post-Joe Paterno era.

The Nittany Lions are off this Saturday before heading to Ohio State.
