#3 Bobby Lashley

"The Almighty" Bobby Lashley has had a mostly uneventful year since his return to WWE.
The biggest "highlights" of his return have been the horrible "Lashley's Sisters" segment, wrestling Elias every week, and making Lio Rush his manager.
Not what many would call an impactful debut.
With Brock Lesnar likely to head into WrestleMania 35 as the Universal Champion, and Lashley needing a major boost in momentum, it wouldn't be unbelievable for WWE to give him a Royal Rumble victory.
Lashley versus Lesnar is considered a dream match amongst the fans because of the similarities between both wrestlers.
Their amateur wrestling background, various world championships, MMA experience, and physique are traits they share, and have many wondering what a match between the two would look like.
Goldberg versus Lesnar from WrestleMania 33 was an epic but short match, and the same thing would probably be expected if Lesnar and Lashley clash.
