An interesting assertion? I'd label it worrying. As to your question, my sense would be that 'yes', our top Clubs would be weaker than a lot of other counties - as an example, Derry, Donegal, Down, Monaghan and Tyrone.
You do raise an interesting point about the number of Clubs we have and I know there are friends of mine, who share my opinion about the standard of Armagh football, who would be steadfast in their view that Armagh has too many Clubs for its population.
As regards the league, I actually think it really works well. Smaller, more competitive divisions, that are linked to the Championship, which maximise the opportunity for meaningful fixtures.
