#3 King Corbin
Despite negative reviews from the WWE Universe, Vince McMahon is still putting Baron Corbin in a significant spot on the shows. WWE brought back the King of the Ring tournament just for the sake of refreshing Corbin's character, and now he calls himself King Corbin.
A superstar can't expect to slay Braun Strowman with strength and would need to use some heelish tactics to overcome the Monster Among Men. King Corbin is the only superstar on SmackDown who can play that role to perfection.
Big men like Strowman never had a long run with a major championship in the WWE, and if history repeats itself, Strowman could also find his name among that list. King Corbin would need some help in overcoming Strowman and looking at the way Dolph Ziggler & Robert Roode are working together with him, WWE can use them to help Corbin win the Universal Championship from Strowman.
