I just want london to get an NFL team so we can have the New England Patriots vs London Red Coats.
Also, do people across the pond actually care for nfl football, as in something you would want to follow?
American football is not likely to become a major sport in the UK any time soon. However it does have quite a big following.
There are lots of teams and fans of the sport, the issue is our education system is primarily based around Rugby, football (soccer), cricket, hockey, netball, tennis, badminton, swimming etc.
Sports such as American football, ice hockey, basket ball, volley ball, baseball, etc etc. Generally only exists as local clubs/teams. This means you need to be interested in them before hand and then join a club.
With more TV coverage/console games etc more people are hearing about these sports and getting actively interested in them. Hopefully this will mean they will get a better, bigger player base in the UK.
Personally my interest in American sports has come from making American friends who have got me interested in playing the console games, then watching, then playing. Without meeting those Americans I don't know if I would have developed an interest in them.
