coordinator? That is the worry I have with extending him; is if he is willing to make that change? I know he parted ways with Ty Detmer and has worked with Grimes and Roderick to shift some of that play calling (supposedly Roderick taking over), but would he be willing to demote or let Tuiaki go and have a significant overhaul of the defensive coaching staff? That may be the sword he lives or dies by.
BTW I agree with what you said.
