Logo of a college football team from the Big Ten Conference, the Iowa Hawkeyes. This logo was used from 1962 until 1970. With all the movement of major college programs from conference to conference in recent years, it’s interesting to note that the Hawkeyes have remained in the Big Ten since 1900. Iowa has had one Heisman Trophy winner in its’ history, Nile Kinnick in 1939, and won the national championship in 1958. The program boasts three Pro Football Hall of Famers in Emlen Tunnell, Paul Krause and Andre Tippett. Other former Hawkeyes who played in the NFL are Alex Karras, Ronnie Harmon, John Niland and Chuck Long.
