Dermot McNicholl. Played minor for 5 years.
He played in five consecutive MacRory Cup finals (1980–1984), winning four of them. He was captain for the last two. (Only one of two men to do that, Greg Blaney's father, Sean, was the other one) He was only in third year when playing on his first MacRory team. In 1980 and 1984 he was runner-up in the Hogan Cup to Carmelite College, Moate and St. Jarlath's College, Tuam respectively.
He won 3 Ulster Minor Football Championships ('80, '81, '83), played in the All-Ireland final each of the three times - winning in '83, as captain.
He won Ulster U-21 in '83, but lost the AI U21 after a replay.
As an aside, though he wasn't still a minor (bad birthday), he won an all star (still youngest ever), played senior inter county and represented Ireland in the International Rules, while still at school.
