It's his first season. They started off hot and the injuries piled up and with the revolving door never really let up. I think he should get at least one more season. Coaches grow in their careers like players do. I bet KK will be better next season than this season.
That said, it really all depends on the HC situation. With a new coach, it's quite possible the new coach will want someone else running the offense. That said, I'm sure KK will get an interview and he'll be coaching somewhere if not with us.
