#3 The Usos set to win the SmackDown Tag Team Championships
Jimmy Uso and Jey Uso have finally been re-united after one year. Jimmy Uso had been out with an injury and made his return a few weeks back on SmackDown.
Even though it looks like Jimmy Uso is not on the same page as Jey Uso and his cousin Roman Reigns, the eventual plan is for The Usos to reclaim the SmackDown Tag Team Championships.
As per WrestlingNews.co, the current plan is for The Usos to win tag team gold very soon. This could be the reason why Dominik Mysterio and Rey Mysterio became the champions, so that The Usos have a babyface team to beat.
