I think Oedenkirk is basically there to give audiences someone they know (Saul!!!) Otherwise, he'd just be a producer. In general, I think you probably shouldn't add new people to a group that's already been working well together (the way Kids In The Hall wouldn't have added new people to the cast when they started…

Although, this is different than a show that, say, casts from auditions or is put together by a network. These guys have been performing together for years, so they just ported over their stage show into this TV show.
