NFL games were first brought to our TV screens over here after the launch of Channel 4 in the early '80s. At that time the Dolphins were the most successful team - think Don Shula, Dan Marino ... They probably have the largest group of UK fans, even now.

Also I understand they have been getting small crowds in Miami, so it makes sense to move the game to Wembley, where nearly 90,000 saw the game.
