I think these characters and the story arcs have been wildly interesting to this point. They've done a fantastic job. We saw plenty of Saul Goodman in Breaking Bad. I don't need them to rush storylines to go back to that place just yet.

Don't get me wrong, I'll be happy to get Saul when we get there I just don't think it's necessary to rush.

Sepinwall interviewed co-creator Peter Gould about this very thing and why they decided that hitting the brakes was better for the story/show:
