Seán Moran, writing in The Irish Times in 2015, described Coldrick as "one of the least excitable referees on the inter-county scene.
What might have been seen as diffidence earlier in his career has evolved into a patient and punctiliously polite demeanour, like a schoolteacher with a difficult class".
[8] At a referee conference in January 2015, Coldrick described missing the chance to show Down player Conor Maginn a black card in the 2014 Ulster Senior Football Championship and not awarding a penalty to Dublin when Cork players handled the ball on the ground during the 2013 All-Ireland Senior Football Championship quarter-final as two of the lowest points of his career at that stage.
[9] Coldrick was referee for the 2022 All-Ireland quarter-final between Armagh and Galway at Croke Park, during which he controversially[10][11][12][13][14] issued straight red cards to both team captains following a brawl before extra-time, while missing Armagh's eye-gouging of Galway forward Damien Comer, which was immediately picked up by television cameras[15][16] and widely condemned.
[22] Coldrick left college in 1997 and joined Irish Life where he is Executive Manager of the Actuarial Reporting team.
