This is pretty much what I am thinking. However, if that running game is successful, the passing game will open up better. Football has a flow to it. Rushing and passing compliment each other. If one of them is not effective, the other also takes a hit. It's not out of the realm of possibility that the offense as a whole sees a significant jump in productivity. Diggs should help in keeping the passing game clicking, just as Moss should help keeping the rushing game clicking. Being successful in both prevents setbacks and keeps the flow of the game from being interrupted. I'm not expecting a huge jump from Josh. But the offense as a whole just might take a leap. If the offense improves only marginally, that would be disappointing.
