I think the last 3 weeks have been enough to save his job. No bullsh!t.
Even if he loses another game, if it's close the perception will be that this is a young team on the brink of greatness. Just watch. He has a built-in excuse with all of the youth on the field right now.
Best case scenario (for the anti Manny crowd) is that they force him to hire a new DC and Manny remains in the CEO\HC role.
They're not gonna send a whole staff packing if we're scoring 35 points per game. Win or lose, the product on the field right now is fun to watch and people currently have hope. I even got that feeling while being at the game Saturday.
A stud QB and high powered offense can change the entire perception of a program.
