O'Hara's inter-county career highlight was his scoring of a brilliant individual goal against Galway in the 2007 Connacht Senior Football Championship Final. His success at putting the football into the back of the net earned him a sponsorship deal of gold boots through parent company Nike. Soon things returned to as they had been before. In 2008, Sligo were trashed by Mayo and ended up in the Tommy Murphy Cup following on from a league campaign that brought relegation to Division 4 – O'Hara said he was embarrassed by the rapid decline back into mediocrity.
