The media is openly speculating that he might return to collegiate coaching. Sal Paolantonio on ESPN discussed it - and it doesn't get much bigger than that, media-wise. If you recall, the Harbaugh rumors began with similar speculation, and Harbaugh kept denying it. We all know how that turned-out.
The question is where he might end-up, provided that he does jump ship in some port not named Philadelphia. It's an internet message board - feel free to speculate. No harm in that, as long as you don't claim that it's "factual".
