American football in Cardiff :-).
I've been watching (a few minutes of) these bad NFL football games played in London. They need something to spice things up. I suggest they ought to play the next NFL game in Cardiff and have The Doctor show previews of the new season at halftime. Might actually get some viewers. I see there is a 74000 seat stadium in Cardiff, that ought to work for an NFL game.
And if we are really lucky the bad teams will disappear into the rift :-).
