The Jags will play 4 games in London from 2013 to 2016 in an effort to build brand loyalty to 1 NFL team. Goodell has noted " the more NFL we give them, the more they want". The next step is to attempt to build loyalty to 1 franchise and Jacksonville has stepped up (in preparation for a move if the experiment succeeds). For the struggling lower market value Jacksonville this is a potential boon. If the NFL can get established in London, the value of that franchise would skyrocket and NFL coffers would expand as the league preps world-wide expansion and domination. 

(All they have to do is figure out a way to make the game safe from concussions, post-career depressions and suicides and debilitating physical injuries. LOL)
