If you played college basketball and contributed to your team you are most likely good enough to play in Ireland, especially if you have an Irish passport. Whether or not you are good enough to play as their American is less certain. Leagues with only one real pro player expect a lot of production. If you just want to play in Ireland and be around family, then go for it, but if you are hoping to climb the ladder you would be much better off in a different league. I did play in the Irish super league.
