#3 AJ Styles
Another rivalry that could have taken off this year was the one between AJ Styles and Randy Orton. During the buildup to Royal Rumble, Orton and Styles were doing a great job at building their rivalry and we saw shades of Orton turning face in the process.
However, an injury to Styles during the Royal Rumble match and a shift in focus to a rivalry between Edge and Orton cut that feud short. Styles moved on to a rivalry with The Undertaker, and the story between The Phenomenal One and The Viper was largely forgotten.
WWE could take this opportunity to revisit their rivalry and take it to new heights before bringing it to a big conclusion. Styles, just like Orton, has lost to a legend at WrestleMania and will be looking for a chance to go after a new opponent.
We could also see Orton assemble a team just like he did with The Revival some time ago and go after Styles, Luke Gallows, and Karl Anderson. Will he look to Ricochet and Humberto Carrillo again to help him take on the heel team?
