Y’all going to hate this. But if it’s WP, it makes most sense to be a shared stadium with the Jets.
1. They just announced they are the UK ambassadors for the NFL already sharing a stadium with my beloved Spurs.
2. They can get out of their MetLife deal in 2025. So the timing is kind of perfect. https://medium.com/@Ihernowitz/there-is-no-franchise-in-sports-like-the-new-york-jets-6bbf999529c0
3. They used to play at Shea, so it would be a return to their original fanbase.
I know you lose some atmosphere with a large NFL stadium, but it would play for large events like the WC. And if you can get that rolling pitch like at TH stadium, it would allow matches Sat/sun no problem.
the only issue is that the stadium wont be anywhere near atlanta / seattle. it will be more like chicago/ NE in terms of atmosphere. also its got to be grass but then it brings the issue of overuse etc. of course if they do it like spurs stadium with one level of field for football and other for soccer its fine.
