#2 King Corbin
Baron Corbin is a part of the SmackDown men's team at Survivor Series. He's the only bad guy in the team, and it is interesting to note that he had issues with Shorty G recently. What's more interesting is that he's currently involved in a feud with Roman Reigns. He even beat the Big Dog last week on SmackDown with help from Robert Roode and Dolph Ziggler.
On this week's episode, Corbin made a mockery of Reigns and brought out a man, who was in a dog costume. This segment was one of the low points of the show, but unfortunately, the feud could continue beyond the PPV. Later in the show, Reigns was ringside as Shorty G and Ali retained their spots on the team after putting it on the line in a tag team match.
As an attempt to get retribution, Corbin could attack one or many Superstars in his team and eventually cost them the match. It would make the most sense as well, considering he has issues with almost everyone on his team.
