The NFL is considering a plan to have a few teams play regularly in Britain to build an overseas following -- part of the league's evaluation about whether a franchise could be permanently based in London. NFL commissioner Roger Goodell said Saturday the league is looking into whether such a scenario would "advance our cause here by growing the fan base quicker." He is talking to several teams about becoming regulars in the British capital, a development he thinks would be "very powerful and lead us to what we ultimately would like to do -- have a franchise here in London."
