Well, since you put it that way, and since rugby is the superior sport, perhaps they should consider political boundaries the way they do rugby boundaries.
Suspect the SNP would agree as well... Nil aon leigheas ar an ngra ach posadh
The difference is that rugby union and cricket, in Ireland, are predominantly middle class sports. Association football (or soccer) is more of a working class game and thus more influenced by the passions of partition.
That is my theory anyway.
