Obviously not aware of the standard of football elsewhere, but I know Cockhill Celtic of the Ulster Senior League have as good as ran away with the league title the past two years, winning league and cup double both those seasons. They came up against Harps this year in the first round of the League Cup, with local football folks claiming they'd easily go through, seeing themselves as a much better team. They got an awful shock when Harps fairly easily disposed of them with a weakened side.
Couple of Junior teams here have fancied beating Harps in pre-season matches too, Erne Wanderers of Ballyshannon being one that were talking up a scalp, saying Harps were 'sh!te' and the usual rubbish sprouted. They got beat 9-0 if memory serves right.
People largely over-estimate the standard of junior football in this country. Any team are capable of a big performance, but the jump in standard from non-league to First Division is huge, as Mervue and Salthill both proved.
The First Division was absolutely woeful for a couple of seasons, but this season has proven a lot closer, more competitive, and quite enjoyable to watch.
