what's the realistic likelihood of the NFL putting a team in the UK permanently ? and who ?

50-50. Spurs' new stadium will have a synthetic turf playing field separate from their natural grass surface that they will use for their home games (it's expected to hold 60,000 which should work for NFL purposes). Toronto Wolfpack have already navigated a regular season in the third tier of England's rugby league comp playing home matches in Toronto but being based in England (so flying out for home games).

I would say about as much chance as an ice cube has to enjoy a week's vacation in Death Valley. There isn't that much interest; I think those games in England are some kind of tax write-off or something.

Not happening.

The NFL should take all the "kneelers" and ship them to the UK. If they don't want to stand for our national anthem and show respect for the flag, let them sit for the Union Jack and watch the hooligans beat on their heads.

I can see them expanding............

Maybe a team or two.....or even a league....

But this is years if not decades away.

slim and none

Zero, for any number of reasons.
