Different Model for Church Leadership?

Somewhat strange question…and I’m asking it in a couple of online forums I frequent…

Do you guys know of any situations/models where the “main teaching pastor” IS NOT the “main leading pastor?” Does that make sense? Are there any churches that are successful where the entrepreneurial/visionary leader is not the one who is most gifted in teaching/preaching? Or conversely, do you know of any successful churches where the most gifted teacher/preacher is not the most gifted entrepreneurial/visionary leader?

I know that sounds kind of weird, but I’m just wondering…thanks in advance for the help!
