On offense the Horns were a total mess in the 80s. There were a (very) few elite level defensive players. These are probably the only guys I'd nominate for an all-decade list.
Kenneth Sims, Defensive Tackle: Lombardi award in 1981, overall #1 NFL draft pick 1982
Jerry Gray, Safety: Two time Consensus All American 1983, 1984
Tony DeGrate, DL: Lombardi winner in 1984, consensus All American 1984
And then maybe Eric Metcalf as a kick return specialist.
