Iowa's dependence on tight end C.J. Fiedorowicz in key moments last season might have left the impression that the Hawkeyes were thin at that spot.
Iowa hopes a deep group of tight ends that played behind Fiedorowicz in 2013 can play bigger roles this fall.
Last season, Fiedorowicz was Iowa's second-leading receiver with 30 receptions for 299 yards and six touchdowns.
He was taken in the NFL Draft in May by the Houston Texans, leaving Ray Hamilton, Jake Duzey, George Kittle and Henry Krieger-Coble behind.
Hamilton said Wednesday that Fiedorowicz's departure has helped foster strong competition for playing time next season.
