Maybe I should have picked a different link that discussed the bureau's overall issues, particularly anticipated budgetary shortfalls: https://www.nytimes.com/2017/07/17/opinion/census-trump-budg...
Yes, the Census is more than its leader, but losing its longtime leader and seemingly not having anyone new (there is a new acting director, IIRC) in place this close to the next census seems worrying.
What's wrong with having an acting director? At least on the corporate side, an acting-whatever is better than "not having anyone new" and many times the acting-whatever becomes the new whatever.
The outgoing director doesn't seem worried.. from your link, when asked if he was worried about there being a leadership vacuum after his departure:
