Dublin continued their dominance in 1976. After securing the National League title 'the Dubs' dominated the provincial championship once again. A narrow 2–8 to 1–9 defeat of Meath gave Mullins a third consecutive Leinster winners' medal. Once again it was Kerry who provided the opposition, as one of the great rivalries of football entered a new chapter. Both sides were hoping for success, however, new 'Dub' Kevin Moran was causing havoc with the Kerry defence. Immediately after the game started he careered through the Kerry half-back and full-back lines, however, his shot at goal went wide. This set the pace for the rest of the match. John McCarthy finished a five-man move to score Dublin's first goal of the day. A converted penalty by Jimmy Keaveney was followed by a third goal from Mullins. A 3–8 to 0–10 score line gave Dublin the title and gave Mullins a second All-Ireland winners' medal. He capped off the year by collecting his first All-Star award.
