#2 Must happen: The OC attack Kevin Owens
Kevin Owens is set to face AJ Styles in a singles match at Starrcade 2019. For now, no stipulations have been added to the match. Although they are expected to engage in an interesting bout, there are several angles that WWE creative can explore.
WWE can have The OC attack Owens during the match which will force another Tag Team to walk out to support him. Eventually, when Owens manages to overcome both Karl Anderson and Luke Gallows, he can be attacked by Seth Rollins. Given the recent alliances between the different members of the Red brand, this particular spot will cause a few notable names to engage in a brawl.
Eventually, this will help set up a great main event for RAW involving multiple Superstars. This could also end up creating new rivalries for WWE to capitalize on moving forward.
