What are the Rams waiting for in announcing their coaching Hires?

We have heard that the positions have been filled, well, if so then why all the waiting to announce them? is their one position they are still waiting on an answer from their choice applicant to accept so they can announce them all at the same time? Seems likely since that's also how they do the draft class.

But I for one am very interested to see who they are filling the open spots with.
