Intercounty season is too long. We should look at only having one premier competition (either a championship or league). Limit the intercounty season to 5 months (March to August). January should be designated a rest month. That leaves us with 6 months exclusively for the clubs.
The League should adopt a format similar to the one which will be used UEFA's Nations League this year. Each division has 8 teams split into 4 groups of 4. Double round-robin so each team gets an equal number of home and away games. The top two teams in each group in Division 1 go into the NFL finals. The 1st placed teams in each group in Divisions 2, 3, and 4 are promoted. The 4th placed teams in each group are relegated.
Min no. of games = 6 Max no. of games = 6 (8 for NFL finalists)
The League is then followed by a two tier championship. Each tier has 16 teams split into 4 groups of 4. Each teams get a home game and an away game. The other game is played in a neutral venue.
Min no. of games = 3 Max no. of games = 6
Every county gets 9-12 games in the season.
The Provincials should be scrapped at senior level but retained for club and underage competitions. The provincial councils should focus solely on development of Gaelic games. Let the GAA worry about running senior intercounty competitions.
