Riker: "Lieutenant Worf, everyone in this room shares my respect for your
service to this ship. But right now, I need your experience at Tactical.
Commander Data, I realize your very nature omits ambition. Nevertheless, I
want you to know that I seriously considered you as first officer."
Data: "Thank you, sir."
Riker: "But this is not the time for change. I need all of you where you are,
where Captain Picard always relied on you. I have been, reluctantly, forced
to conclude that Commander Shelby, our expert on the Borg is an ideal choice
at this time for a first officer."
