I also don’t think they’ll ever come up with a viable solution to the travel burden that will be forced on the London team. Also the tax / exchange rate could be problematic. We already see the trouble Canadian teams have with this in other leagues which is a large part of the reason no Canadian team has won a Stanley Cup in about 20 years.
That’s been the main argument against a UK NFL team. The logistics are a nightmare. Teams already struggle just going coast to coast. I imagine a UK team wouldn’t many road games.
I have a feeling it will stay the way it is for a while. The teams that sacrifice a home game to the UK typically see a financial gain as those games are actually quite popular there.
