If GM holding Marvin back, then why has Marvin never left to a better Opportunity/GM?

[BengalChris]

The entire Bengals franchise is a victim of Mike Brown's management, not just Marvin Lewis.

But instead of asking why Marv hasn't left, maybe ask why no one has offered Marv a job somewhere else? Remember last year in the final game of the year, it was "Marvin's last game as the head coach of the Cincinnati Bengals."

That game ended and we were all then talking about who might a good HC for this team. The next day we were talking about who the next coach might be. Marv was available right then and any other team could have at least made overtures toward Marv's agent. I'm guessing no one was.
