I agree to a large extent.

For myself, I'm the most productive when I

- Am able to influence what I work on, and choose how I solve a task

- Have tasks lined up in a front of me that I can choose to work on

- Am in a state of flow, where the tasks in front of me roughly corresponds to my skills.

In other words - to me - a good project manager makes sure that there are plans for what to work on next and that the tasks roughly corresponds with the teams strengths.

Now, that roughly corresponds with good "backlog grooming", but not sprints.

Basically, I think Kanban works much better.
