Just like with Ciampa, when Vince starts off with a talent by changing the presentation (be it aesthetics, name, gear, etc), those guys are already DOA because he doesn't understand what makes those talents who they are or why crowds connect with them to begin with. So he changes and tries to mold them into what he thinks they should be, it doesn't work, he gets tired of the new toys, and then they're eventually cut. This applies to Pritchard as well, who is probably really the one behind this more than Vince directly.
