In 1950, the Illinois Intercollegiate Athletic Conference, which had dwindled down to only five members (NIU, SIU, EIU, WIU, and ISU) accepted its first members from out of state and changed its name to the Interstate Intercollegiate Athletic Conference. With the exception of the spotless season (9–0–0) in 1951 that earned the team a 5th conference title, NIU failed to make a decent showing during the first few years in the newly named conference. Howard Fletcher though had other plans as he picked up the pieces of the miserable 0–8–1 season from Robert Kahler in 1956. The Huskies' had a slow progress that picked up in the late 1950s. The team's third bowl game appearance in 1962, although a loss, was only the beginning of good things to come as in the following season, the Huskies completed their sixth undefeated season which earned them the Interstate Intercollegiate Athletic Conference Championship, an AP College Division National championship selection, and a ticket to the prestigious Mineral Water Bowl which the team eventually won over Missouri State. The team made it a three-peat championship, adding up the 1964 and 1965 conference titles. NIU became independent from 1966 through '72 before joining the Mid-American Athletic Conference in 1973. The team claimed the MAC title in 1983 then went on to their first Bowl Game in the Division I-A, the California Bowl, which the Huskies won over Cal State-Fullerton. The team left the MAC after the 1985 season and first became independent from 1986 to 1992, then joined the Big West Conference from 1993 through '95, becoming independent again in '96, then finally was admitted back into the Mid-American Conference in 1997.
