The 1977 Leinster final was a replay of the previous year with the result being the same. Meath provided some stiff opposition but fell short, eventually losing the game by 1–9 to 0–8. It was Mullins's fourth consecutive Leinster title. Dublin later took on Kerry for the third consecutive year, however, this time it was in the All-Ireland semi-final. In one of the greatest games of football ever-played 'the Dubs' triumphed and booked a final spot against Armagh. An eight-goal thriller ensued, with Jimmy Keaveney scoring the first of the day after just ninety seconds. He ended the day with a record 2–6 from play. Bobby Doyle soon followed with the first of his two goals while John McCarthy got a fifth. Armagh were awarded two penalties, however, the northerners spurned some golden goal-scoring opportunities. A huge 5–12 to 3–6 victory gave Dublin a second consecutive title and gave Mullins a third All-Ireland winners' medal in four years. He was later presented with a second All-Star award.
