Well since his contract is expiring, if the previous agreement was for him to let Brunette take over, but he still wants to coach now...he can choose to go to another team. I'm sure some team is willing to take his services given the success of this season. But again, this only makes sense if my speculation is correct that they had a previous understanding that he wouldn't get extended in favor of letting Brunette take over after this year. If they haven't had that discussion, and he tells Fitz he wants to say, I can see how it might be difficult to say no.
