From Wikpedia: A spin-off is a radio program, television program, video game, or any narrative work, derived from one or more already existing works, that focuses, in particular, in more detail on one aspect of that original work (e.g. a particular topic, character, or event).

No way a spinoff, just used two actors/actress from the show.
Sam and Cat would be a spinoff of iCarly. It involves the same characters, unlike D&J and iCarly.
