Shake-up in the Mayor's Office?

With the start of the second term, I've heard a couple of rumors about this person or that leaving. Without confirmation, I'll uncharacteristically refrain from passing them along, except this one which is the most interesting of them.

Rainford moves to a special position to explore "regional options", and Sam Simon goes from Public Safety to Chief of Staff. Satisfies the Rainford haters and sets the table for a major strategic initiative towards more city-county consolidation.
