Kirk Cousins Not Recognized By Die Hard Redskins Fan

This is a fun and interesting tweet from the Washington Redskins backup (or next year's starting quarterback...ug) Kirk Cousins.  He claims that a Redskins fan asked him if he was a Redskins fan himself, not recognizing him as an NFL player.

Is it a lying "die hard" fan?  Is it the haircut? Or is it just the life of a backup QB in the NFL?  I've noticed the same thing as the following Tweeter

Unfortunately in 2013 every Redskins fan may be forced to recognize Kirk or Kurt Cousins, whatever they call him, it won't be RG3...
