#1 Samoa Joe

Last but definitely not least, we have The Samoan Submission Machine in Samoa Joe at #1 on the list. Joe arrived on Smackdown Live as part of the Superstar Shakeup, but he has yet to make his mark on the roster despite having a great feud with AJ Styles for the WWE Championship- in a rivalry that he lost.
Joe has also proven that he can go face to face with Brock Lesnar as he gave Lesnar quite a fight at The Great Balls of Fire 2017 event. Lesnar successfully defended the WWE Universal Championship against Joe. The main event scene on Smackdown Live is filled up with the likes of AJ Styles and Daniel Bryan, therefore Joe could benefit from competing for the US Champion.

A rivalry against Rusev would be something that we haven't seen before, and it would be great considering the fact that the two men have similar physiques and they are both very hard-hitting. It would pave the way for brutal matches between the two as it would be a fresh match-up.
Putting the US Championship on Joe would help his career, and it would establish The Samoan Submission Machine as a serious threat on the main roster. Joe desperately needs something to do in order to boost his reputation, which is why a rivalry and a championship win against Rusev could be best for business.
