McDyer won his first
Donegal Senior Football Championship title with his club in 2005. His free in the 2005 final brought that game to a
replay, when he scored 0–3 (including one free). 2005 was also the year he first played for his club in the senior championship. When McIver called him into the senior team, McDyer was 18 years of age. Naomh Conaill went on to reach the final of the 2010
Ulster Senior Club Football Championship, knocking out Cavan champions
Kingscourt, Monaghan champions
Clontibret and Tyrone champions
Coalisland along the way. Towards the end of the
2012 Donegal Senior Football Championship final, McDyer tried to pass the ball back to goalkeeper Stephen McGrath, but his action caused Naomh Conaill to concede a '45. This was converted by
St Eunan's player
Mark McGowan, and Naomh Conaill lost the game by one point. McDyer played for his club in the final of the
2015 Donegal Senior Football Championship. His club also won this game, with McDyer scoring 0–2. Then he played for his club in the final of the
2019 Donegal Senior Football Championship. His club won, following a second
replay; McDyer started all three games and, though he scored 0–1 in the first game, he was held scoreless in the second and third. Then he made a substitute appearance for his club in the
2020 Donegal Senior Football Championship final. His club won, following extra-time and a penalty shoot-out. Then McDyer played for his club in the
2022 Donegal SFC final. His club won, with McDyer scoring 0–3, though at least one source erroneously said 0–2. He was troubled by injury at the time.
RTÉ Raidió na Gaeltachta announced the decision. McDyer was not expecting to be selected. He received the award at an official function in
