#1 Replacing Roman Reigns
One of the biggest losses WWE faced recently was that of Roman Reigns.
Roman Reigns recently announced that he was suffering from Leukemia and as a result would have to take a hiatus from wrestling and WWE to deal with it.
For the past 5 years, Roman Reigns has been booked by WWE to be the face of WWE. Now, with Reigns gone, WWE has suddenly been left without a single face for WWE fans to look up to.
For this reason, 2019 will be a huge one for WWE. They will have to find a way to replace Roman Reigns.
This will prove to be quite a challenge for anyone superstar to do. It's not that WWE has a shortage of candidates for the role, with Drew McIntyre and Braun Strowman both having the potential to fill the slot.
Given that Lesnar is the temporary Universal Champion, it will be interesting to see how WWE book whoever they choose as Reigns' replacement.
