Should Joe Gibbs be let go or retire?

[SC Skins Fan]

One issue with cleaning house that I have not heard addressed (which doesn't mean it hasn't been addressed) is what happens to Jason Campbell. Anecdotally at least, it seems that often times when a team changes course early on in the development of a young QB that QB drifts off into oblivion. The group that drafted him, had faith in him, and had staked their reputations to him are gone and the proverbial chain tends to get a lot shorter. The new staff will sometimes bring in their own guy, who they want to develop, and they just aren't willing to weather the storms with someone else's choice. Obviously if Gregg Williams were to take over it would be different, but other than that what happens?

Two that come to my mind immediately are J.P. Losman and Phillip Rivers (err, Pat Ramsey?), and maybe I'm extrapolating too much, but it just seems that when teams change direction before a young QB has really established himself it doesn't work too well for the QB.

Edit: and add Matt Leinart this season prior to his injury.
