After holding four-team playoffs after the first three I-AA seasons, the NCAA increased the bracket size to eight this postseason. It grew to twelve in 1982 and sixteen in 1986. The eight-team field was determined via automatic bids to five conference champions (Idaho State, South Carolina State, Eastern Kentucky, Jackson State, and Rhode Island), a bid to the top-ranked independent team (Tennessee State), and two at-large bids (Boise State and Delaware).[4]
