#4 King Corbin
King Corbin could also be a member of Team SmackDown at Survivor Series 2019. Despite winning the King of the Ring tournament, he hasn't been as prominently featured as he should be. Fans have gotten a little tired of his shtick, but it's undeniable that he has improved leaps and bounds over the last year.
After his feud with Shorty G, he was a part of Team Flair at Crown Jewel 2019, where they lost to Team Hogan. He's also had some issues with Roman Reigns and picked up a feud against The Big Dog a few weeks ago. During last week's episode, they collided in a match, and Corbin won with the help of shenanigans.
This extends the feud as expected and could play a part in deciding SmackDown's fate at Survivor Series. If both these men are on the same team, they could focus on each other instead of working together, which could cost them the match. Therefore, Corbin should be on team SmackDown to create some intrigue.
