A nonsense argument Walter is putting forward, Colleges football is a super standard, much more Darwinian than some underage county panels.
IMO Tyrone' Schools' biggest advantage is that it is a huge county comparatively speaking with much greater nationalist leaning people (strong communities & clubs) than other counties. Gaelic football is king everywhere as well, little Hurling, Soccer, even Basketball? ( I remember Dungannon used to be a BB powerhouse but do they bother with it anymore?). In A grade Armagh have 2 regular MacRory teams, St Pats Armagh & St Ronans Lurgan and up until the creation of Ronans, St Pats were the only A grade side, and a lot of our catchment area are Armagh clubs near the Tyrone border who gravitate towards Dungannon Academy. St Paul's Bessbrook flit between A & B grade and they have to contend with half of South Armagh going to Newry Schools. But that is just the way it is, there aren't going to be any structural changes that can level the playing field a bit.
