Who do you blame for Jason Campbell not reaching his full potential in the NFL Jason Campbell or the Redskins?

I place all the blame on the Redskins for a few reasons. One year in and out they had a different coach and different offensive coordinator which made it hard for him to get completely comfortable with the offense from year to year. Two they didn't put enough trust in him when they did let him run the offense but then again well it's as if he wasn't running the offense when he couldn't even call an audible at the line of scrimmage without looking to the sidelines first.
