#4 Kevin Owens
With Survivor Series coming at WWE next after TLC it's likely any feud started now could wind up culminating in Survivor Series. Dave Meltzer noted on Wrestling Observer Live that he expected more than just one cross-brand match at Survivor Series this year.
It appears as though Kevin Owens and Randy Orton might be starting a feud on SmackDown Live, but that could always be put on the backburner to allow Kevin Owens the opportunity to jump company lines and get in Braun Strowman's business next.
KO and his best-friend Sami Zayn could pull another surprise out of their back pocket and show up on Raw to ruin Braun Strowman's day. This could result in some amazing back and forth across WWE brands requiring fans to tune into both shows in order to see the entire captivating storyline develop.
