I agree with truncating the duration of the league: 30 league matches at 30 weekends, with a few extra weeks for the FAI cup seems feasible, and allows for a mid-season break. And I would do away with play-offs entirely: final positions should be decided when the league is over, not by play-offs, firstly within and ultimately between divisions, which are more like cup ties tagged on at the end and as like as not to be settled like a cup-tie - by a stroke of bad luck. In a 16 team division, I’d prefer to see two down, two up. I’d suggest three, but until there’s a clearer view of what teams would be in the first division, it might be a step too far for the third-placed team and harm them in the long run.
As to whether I prefer summer or winter soccer, like the seasons I blow hot and cold! Both have their attractions; both have their detractions. But blaming balmy summer nights in Bray, or sleet and snow in Sligo for poor attendances just gives me the impression (again) that some clubs and the league need to stop looking for excuses for their promotional deficiencies, get off their collectives asses and fight for custom. Ten teams, sixteen teams; teams from “the provinces” or only from the Pale; pyramids or ever decreasing circles – it’s all tinkering at the edges if the basic marketing and public relations efforts are missing.
