In 2014 Delaney deputised as captain on a number of occasions due to the absence of regular skipper Lester Ryan. That year he collected his eighth league medal, as Kilkenny secured a narrow one-point 2–25 to 1–27 extra-time victory over Tipperary. Delaney subsequently secured an eleventh Leinster medal, as a dominant Kilkenny display gave "the Cats" a 0–14 to 1–9 defeat of Dublin. On 7 September 2014, Delaney led Kilkenny onto the field for an All-Ireland decider with Tipperary. In what some consider to be the greatest game of all-time, the sides were level when Tipperary were awarded a controversial free. John O'Dwyer had the chance to win the game, however, his late free drifted wide resulting in a draw. The replay on 27 September 2014 was also a close affair, with Delaney's hook on Séamus Callanan being a high point. Goals from brothers Richie and John Power inspired Kilkenny to a 2–17 to 2–14 victory. It was Delaney's eighth All-Ireland medal, while a seventh All-Star award quickly followed.
