I hope the "language" is a LOT of language. To start with, I hope it says we have to win the AFC championship in those two years. Then, I hope it guarantees that the coach gets to make the calls as to who plays. Further, it should indicate that non-players won't ever fill more than one job - so he has to hire people to do jobs, then let them do them unafraid of him.
I'll think of more "language" that would help this team. But suffice it to say the language will be performance based... You get it done, or you're gone...now sign on the line!
