Thanks for the examples. I don't follow NBA. As for Cardiff, last thing on my mind really.
Us being at the north did come to my mind, though. It certainly does make things easier. However, if we do it (or Bayern, or whoever), I see more teams following. In such case, there would be clubs from all over the country, whether that's south or east, and it kinda makes it difficult, no? I'm not sure if that's a good thing for football because I doubt it'd stop at Juve doing it. Seeing leagues mixed and matched is kinda meh imo. The first thing that comes to my mind is Super League which would happen as a result of many clubs rioting out.
