The offseason turmoil did not help the 1970 Hawkeye squad, which finished 3–6–1. At the end of that season, Nagel had had enough of the emotional roller coaster at Iowa and abruptly resigned. Elliott hired Frank Lauterbur to replace Nagel. The program hit rock bottom, as Iowa went 4–28–1 from 1971 to 1973 under Lauterbur. That included an embarrassing 0–11 record in 1973, the only winless season for the Hawks since Iowa's first season in 1889. The highlight of Lauterbur's tenure at Iowa came in 1972, when Iowa Stadium was officially renamed Kinnick Stadium, in honor of the 1939 Heisman Trophy winner.
