In re-watching some of Discovery I once again questioned the story's need to use Spock or Pike's Enterprise. Then I recently re-watched the TOS episode "Doomsday Machine," and thought Discovery's story could have just as easily been told with a younger Matt Decker and crewmembers from the U.S.S. Constellation. It would have given the story a lineage all the way to ST: TMP without the goofiness of making Michael Burnham the foster child of Sarek and Amanda yet still preserve one of the most effective scenes whereby a Starfleet captain glimpses his tragic fate.
