It's a tricky situation.
It would be great for Galway to be included in Leinster at under 21 and minor level. It would be beneficial for the stronger Leinster counties as well. Teams like Wexford, Kilkenny and Dublin have dominated the province over the last few years.
The downfall for including Galway would be for the weaker counties within Leinster, the likes of Offaly, Westmeath, Carlow, Laois. Does Galway inclusion hamper the development of these counties? Does it drive them on to improve, or does it drive more players away from the game?
Leinster council may state that they have a commitment to the weaker counties rather than the stronger counties.
I personally think they should be included across the board.
