#4 The Dirty Dawgs vs RK-Bro
RK-Bro would have more than a contest on their hands if they were to go up against Robert Roode and Dolph Ziggler, referred to as The Dirty Dawgs.
The Dirty Dawgs have been really impressive since the very beginning of this year. They beat The Street Profits to become the SmackDown Tag Team Champions and, at WrestleMania 37, Roode and Ziggler defeated Alpha Academy, The Mysterios, and The Street Profits in a Fatal 4-Way match to retain the titles.
In April, Ziggler and Roode had another successful defense, beating The Street Profits. Their impressive 128-day title run finally ended at WrestleMania Backlash at the hands of The Mysterios.
With such caliber on display, RK-Bro will surely have a compelling storyline against the former SmackDown Tag-Team Champions.
#3 The Mysterios v RK-Bro
This rivalry could see two legends square off again in Randy Orton and Rey Mysterio. Having been in singles competitions throughout their careers, seeing them in a tag-team rivalry would be riveting.
Rey and his son Dominik are the quintessential babyfaces having held the SmackDown Tag Team Championship for 63 days before losing it to The Usos at Money in the Bank. A contest with RK-Bro would pin top fan favorites from both brands.
