I'm sure I already said that a couple of pages back.
The request from CBS was that there shouldn't be a 1701-F if the E is simply MIA. And the fact that the crew of the Enterprise (ANY Enterprise) would be able to get out of any trouble they may find themselves in.
The post in the STO forums specifically calls for an Admiral, so Picard was out from day one; as in the STO lore, he never made Admiral (I like to think he took Kirk's words to heart in Generations). I can easily see Tuvok, Data or Riker as some sort of Admiral by 2409, Perhaps even Geordi LaForge... (Head of the Starfleet Corps of Engineers perhaps?)
