#2 Baron Corbin
While there are many rumours about why Baron Corbin has landed himself in the doghouse with WWE, including a confrontation with a backstage doctor over concussions and an incident with John Cena, that's not why he's on this list. Why he is on this list, however, is because he seems to lack personality or any kind of faith from backstage officials.
He seems to know how to make other Superstars mad, as he is also rumoured to have had a backstage incident with John Cena, which is said to have prompted the unsuccessful cash in and subsequent loss to Cena at Summerslam. In the end, there's nothing positive right now about Corbin and that trend looks to continue in 2018.
Furthermore, he also lost the United States title at Clash of Champions after a lacklustre run with the belt.
