I would say that one route in particular would be a pretty close approximation of the running game. However, it depends on what the receivers are doing. If they're blocking all the way, then yes. If they're running the DBs off, the defense would have to be playing it like a pass so I don't get how that would be much similar to the running game. I don't remember us running a lot of them in the last couple years though we did "fumble" one against Oregon last year.
The other one would be a shovel pass but I don't remember us running those in the last couple years.
But I think a lot of people will just say "Look! Our RBs caught five passes this game but those are really like running plays." And I don't think that will be very accurate.
