Probably because of Spider-Man.
[Latino Review](http://www.latino-review.com/news/exclusive-drew-goddard-has-left-marvels-daredevil) broke the news that Goddard is off the show and [THR](http://www.hollywoodreporter.com/live-feed/steven-deknight-set-as-daredevil-703693) is reporting that Steven DeKnight, long time Joss Whedon collaborator is all but set to take over.
This hasn’t been a good weekend for Marvel what with Edgar Wright leaving Ant-Man but at least this news has more clear reasoning. Goddard is also set to direct Sony’s Sinister Six movie as well as DareDevil and with Sony ramping up production on their movies to try to make up for Amazing Spider-Man 2 tanking at the box office he likely simply had too much going on and needed to focus on one or the other. In this light, and with the fact that movies will always be more prestigious, it kinda makes sense.
