#4 Bobby Lashley

Lashley made his return to the WWE on the 9th April 2018 on the Raw after Wrestlemania 34 as we saw Lashley confront Elias and attack him to a huge pop from the fans. But despite the positive ovation he first received, Lashley has been floundering ever since his big return to Monday nights.
We have seen Lashley involved in many tag team matches, and he has been involved in rivalries that have either not had a pay-off, or he has simply lost them. And that is very frustrating considering the fact that Lashley is a legit competitor in real life. He has competed in MMA as he has an impressive 15-2 win-loss record which goes to show that he is as real as they came.
Really, he should've been booked just like Brock Lesnar- but instead, we saw seen him lose matches to the likes of Elias and Roman Reigns. Lashley is currently involved in a Tag Team with Lio Rush, which could be beneficial for both men if booked currently. However, we've been seeing Lashley succumbed to slapping his own bottom which is disappointing considering the fact that he should be seen as a serious threat.
On the December 31st, 2018 episode of Raw, we saw Lashley being brutally attacked by Seth Rollins with a steel chair after Triple H had told Rollins that he wanted to "see the old Seth Rollins." This could provide great reasoning for Lashley targetting Triple H, as he could state that Rollins chose to make a statement at the expense of Lashley and it was all because of Triple H's words.
It would also make sense for Lashley to go after Rollins, but we've seen that match before at Crown Jewel- which doesn't make it Wrestlemania worthy at all. Seeing Lashley & Hunter face off in a match would be very hard-hitting and exciting, and it could be a great opportunity to give Lashley the credibility that he needs.
