At the north end of the stadium is the Howard Schnellenberger Football Complex, which houses the football offices and the conditioning center for the football team. Also at the north end is a bronze statue of Johnny Unitas, NFL great and the most famous football alumnus of the university. The seating expansion in the North end zone is loosely based on the North end zone seating structure of the NFL's Seattle Seahawks Lumen Field. As part of game day tradition, each Cardinal player touches the base of the statue before entering the field prior to kickoff. In 2006 the $10 million Trager Center, an indoor practice facility opened just north of the Schnellenberger Complex, providing a dry and warm area to allow undisrupted practices in Louisville's highly variable weather.
