#4 The Promos!
Remember John Cena verbally squashing Roman Reigns on the mic in 2017? Remember Samoa Joe relentlessly tearing apart the likes of Brock Lesnar, Jeff Hardy, and AJ Styles? Combine both these and we get a promo battle for ages!
Joe and Cena are two of the best mic workers in the company. They have charisma and a great personality which sets them apart from the less-talented promo-workers in the company.
If Joe and Cena just give us 3-4 weeks of epic promo battles, it will be much better than anything WWE has done in the last few years!
#3 Secondary Championships need credibility
The US Championship has been neglected significantly ever since the brand split. AJ Styles tried to make it relevant but even he couldn't create magic with Kevin Owens.
Samoa Joe is an individual who can restore the greatness of the historic title. What better way to make it prestigious once again by bringing back John Cena to compete for the championship!
