#1 Lars Sullivan

Whether the WWE Universe likes it or not, Lars Sullivan is an absolute force to be reckoned with and would have been a great addition to the Smackdown Live side of the men's Money in the Bank ladder match. In fact, it would have been a great way to showcase what he could do in the ring and even what he could do with weapons at his disposal.
Beyond that, Sullivan is one of those superstars that WWE seems to be high on right now, which would make it very interesting to watch whether he came out of it all with the briefcase or not. In the end, maybe some will see it as too soon or even that Sullivan is undeserving, but what would he really lose by being in this kind of match?
Furthermore, Monday Night Raw picked a heavyweight in Bruan Strowman, thus making it very one-sided that Smackdown Live doesn't have their own heavyweight competitor in the match as well. Even if WWE didn't want Sullivan to lose credibility, they could have still set him up in a big spot and then not involve him in the finish. Keeping him out entirely just seems wrong.
