I know some people are against black jerseys, but I had a wild idea (I do mean wild).
Black jerseys with black pants and green tartan numbers. One side of the shoulder is a black interlocked ND, and the other side is the country of Ireland.
Sounds crazy, but I think it would look pretty slick with the gold helmets.
I'm also for green numbers in Ireland game.
At least you weren't suggesting they play in Ireland in black and tan.
