During his career at Penn State, Shipley switched positions on the offensive and defensive lines, several times. Shipley's redshirt freshman season at Penn State began with him playing on the offensive line and ended with him playing defense. At the beginning of the 2006 season Shipley was switched back to the offensive line and he spent the season as the starting center and anchored the offensive line for Tony Hunt's record-setting senior season. Shipley is known for his engaging personality and has served as the team Santa Claus for the Nittany Lions' annual Christmas party. He is known as a team leader who has sought out leadership positions.  I just love being a leader, love being the center, knowing that the play starts with me and being able to control the offensive line, when I played high school basketball, I loved having the ball in my hands for the last shot. I like to be able to try to raise other people's play. Shipley began the 2008 season on the Lombardi, Outland, and Rimington Trophy watchlists. By October, he had earned mid-season All-American honors from Sports Illustrated, College Football News, CBS Sports, and Phil Steele.
