UnderArmour are starting to market Cam over here in the UK the same way Nike do with LeBron James. They know that because the sport isn't major, name recognition isn't enough. Most people in the UK know LeBron James as that Basketball guy and hopefully soon Cam will be that NFL guy. Then if the NFL kicks off big time over here Cam will already be the face of the NFL over here.
A UK team would probably be bad for the NFL but great for Cam, I think he would instantly become huge in Europe thanks to UnderArmour.
