Who Ya Got: Marvin Lewis or Mike Zimmer?

I would choose Zimmer because I believe we have seen the best of Marvin and Zimmer's best is still an unknown. I saw a chart a few weeks ago that showed the four most tenured coaches in the NFL, and Marvin has by far the lowest winning percentage of any. I know, I know... "look where the franchise was before him". I think he is owed a debt of gratitude for turning it around, but I don't see him being able to take this franchise all the way.
