#3 Joining Kevin Owens

Kevin Owens has been feuding with Daniel Bryan ever since Vince McMahon named him as the replacement for Kofi Kingston. One aspect Owens has fallen short of is in the numbers game.
Daniel Bryan has Rowan as his bodyguard and the monster has definitely done damage to the Prizefighter.
In a recent episode of SmackDown Live, Mustafa Ali made the save for Owens against Bryan and Rowan. But that was more because of a common enemy. For a large part of his stint in WWE, Owens always has had a partner in crime.
From Chris Jericho to Sami Zayn, some of the most defining moments in Owens' career has been when he has a partner. Owens even rued the fact that he no longer has any friends.
Harper can fit perfectly because he has a history with both Rowan and Bryan. He can be the equalizer for Owens against Bryan and Rowan. And when the impending implosion happens, as it does for with all of Owens' partners, they can have a decent feud going forward.
