Jrue Holiday is like the best case scenario for what Exum could eventually be if you gave Jrue a little more speed + length but took away alot of his strength, so if you think the Jazz are still a 1st round exit with Jrue running the show then idk what to tell you. Stats suggest they have a very similar playstyle (e.g. similar %s of shots at the rim), and even though Jrue isn't a pure point I don't think Exum really is either, but both are elite at putting pressure on the rim consistently from the guard positions.
edit: well, a healthy Exum who isn't rusty at least.
