The exhibit: The "AT&T Game Time" gallery focuses on rivalries and memorable moments.

Touring it: Among the artifacts are the orange uniform pants that Clemson wore against rival South Carolina for the first time in 1980 and the original "Paul Bunyan axe" that is given annually to the winner of the Wisconsin-Minnesota game. And there's the bowl and spoon from which flu-ridden Joe Montana ate chicken soup in the locker room before returning to rally Notre Dame to a memorable victory in the 1979 Cotton Bowl. Also in this wing, fans can don headsets, listen to the radio call of their team's iconic plays and record their own call. Or transport themselves to a historic stadium via 360-degree viewers.

Talking about it: For all the focus on fan experience in the building, "you still have to have all the greatest games, greatest moments (represented)," said Patrick Gallagher, president of exhibits designer Gallagher & Associates. "Those are all in there. But you may get to them in different ways."
