#3 John Morrison
John Morrison made his return to WWE in January this year after a gap of almost nine years. Upon returning, The Guru Of Greatness teamed up with his former tag team partner, The Miz. Morrison's first match after his return was against Big E of The New Day, which Morrison won with some assistance from the A-Lister.
Morrison and Miz eventually became SmackDown Tag Team Champions, when they defeated The New Day at Super ShowDown back in February. The two then successfully defended their titles inside the Elimination Chamber match at the namesake event. Morrison recently defeated Kofi Kingston and Jimmy Uso in a Triple Threat Ladder match to retain the SmackDown Tag Team Championship at WrestleMania 36 this past weekend.
Even though Morrison and Reigns haven't been on the roster together for long, there is some history between the two. Back in 2016, Morrison stated in an interview that he would love to wrestle Roman Reigns in 10 years, because by then he'd figure out how to work.
Earlier this year, Reigns took a shot at Morrison during a Twitter exchange between The Miz, Morrison and Reigns. Reigns sarcastically acknowledged Morrison's presence and promised a beating for him.
The seeds for an inevitable feud between Reigns and Morrison have been planted. Their personal tensions could even propel their feud to new heights.
