No question that Noah's value to this team is much less than last year. But that leg should get better in the off season. Ans, while he may not be 100% of what he was, he still should be a very good player. As I see, it, he and Gasol should have one more productive year together and then they need to decide how to re-do their bigs which they will have to do, including Gibson.
This doesn't need to be a housecleaning but they will have to move two or three players and get some younger guys in. And they will need backcourt help.
