Because Y: Marshals is merging the world of cowboys and lawmen, expanding on Kayce Dutton's (Luke Grimes) history as a Navy SEAL and highlighting the struggle that U.S. Marshals face when they spend time apart from their family, the show has some real potential beyond anything the original Yellowstone could ever muster. Taking down Montana-based criminals will certainly be a draw for this show, as will furthering the story of Kayce and his family, but there's one character that (in light of the subject matter) ought to be further explored on the upcoming CBS drama: Jake McLaughlin's Cade McPherson.
