5 WWE Superstars John Morrison could feud with if he decides to return 

#2 The Miz

In terms of history, there's no one in WWE that Morrison has more with, as The Miz has been his partner and rival during Morrison's first stint in WWE. The Miz has improved out of sight since the two were last in the ring together, but have remained friends behind the scenes, and it's a rivalry that both men would love to reignite.

The Miz needs a heated rivalry to get him going again, and if WWE can bring back The Shaman of Sexy, they'd no doubt have a killer feud going into SummerSlam or Survivor Series. Morrison has made it clear in interviews that he'd love to have one last feud with The Miz (and perhaps even team with him), and if he is to return to WWE sometime in 2019, this is the rivalry that should re-introduce him to the WWE Universe.
