Ó Sé's first National League medal. He later made his championship debut against Waterford. In 1975, a new-look Kerry team was formed under the management of former player Mick O'Dwyer. It was the beginning of a glorious era for Kerry football and Ó Sé played a key role in orchestrating much of the success for the team that would come to be regarded as the greatest of all-time. That year he won his first Munster medal, dethroning Cork as provincial champions in the process. Ó Sé later lined out in his first senior All-Ireland final. Reigning champions Dublin provided the opposition and were installed as the red-hot favourites over the youngest Kerry team of all-time. On a rain-soaked day John Egan and substitute Ger O'Driscoll scored two goals and the Dubs were ambushed by 2-12 to 0-11. It was Ó Sé's first All-Ireland medal at senior level. Ó Sé later said, "To this day, winning that All-Ireland medal is my greatest thrill. The oldest person on the team was Brendan Lynch and he was only 25. Nobody gave us a chance: we were just a team of 15 bachelors from Kerry up for the day". Ó Sé captured his second Munster medal in 1976 before later lining out in his second All-Ireland final. Once again it was Dublin who provided the opposition. Both sides were hoping for success; however, new player Kevin Moran was causing havoc with the Kerry defence. Jimmy Keaveney converted a penalty to help Dublin to a 3-8 to 0-10 victory and defeat for Ó Sé. 1977 proved to be another frustrating year. The year began with Ó Sé capturing a second National League medal and a third consecutive Munster medal following another win over Cork. Kerry later took on Dublin 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 Ó Sé was still left waiting for a second All-Ireland medal. In 1978, Kerry once again faced little competition in the Provincial Championship. A 3-14 to 3-7 defeat of Cork gave Ó Sé a fourth Munster medal in-a-row. Kerry later qualified for a third All-Ireland final in four years. Old rivals Dublin provided the opposition; however, the game turned into a rout. The game is chiefly remembered for Mikey Sheehy's sensational goal. The Kerry forward lobbed the ball over
