After exchanging some hot words with AJ Styles last week, Orton took him on later in the night.The two men did well in the contest before Riddle leveled Omos outside the ring to help Orton win the match. Afterward, The Viper RKO-ed Riddle to make a statement.The events of this week's RAW have given Orton and Riddle a chance to get on the same page again, especially now that they are the upcoming challengers for Styles and Omos' titles."#RKBro is back together! It means at #SummerSlam, #RKBro is gonna challenge @AJStylesOrg & @TheGiantOmos for the #WWERaw #TagTeamTitles!"@SuperKingofBros @RandyOrton pic.twitter.com/QM9lPl1U5o— WWE (@WWE) August 17, 2021RK-Bro can realistically defeat AJ Styles and Omos without hurting the latter team's credibility.After all, SummerSlam, being a huge pay-per-view, is the perfect stage to have the RAW Tag Team Championships change hands. Such an outcome should also give Riddle and Orton a big boost and ensure that they stay together for some time.
