#4 Bobby Lashley

While Bobby Lashley remains one of the least liked WWE Superstars on the roster, especially after his wedding to Lana, he is building up quite the streak in the process. In fact, between his win over Rusev at TLC and his subsequent victory over The Bulgarian Brute recently on RAW, it looks like WWE has plans for Lashley.
What makes this situation even more interesting is the fact that Bobby Lashley versus Brock Lesnar has been considered a bit of dream match, which is why WWE might want to go forward with it. Lashley himself has said that he returned to WWE because he wants to wrestle Brock Lesnar.

In the end, Lesnar might just be too big of a dream match to pass up. Furthermore, the addition of Lana as Lashley's manager has given him a mouthpiece that could carry him to the top of the card. Whether that actually ends up happening or not remains to be seen, but one would be foolish to admit that the pieces aren't all there.
