#7 Sami Zayn - 16/1
It was hard not to love Sami Zayn during his run as a babyface, and now, as an over the top heel, it's hard not to find him incredibly annoying - but in the best way possible. The Underdog from the Underground has forged a dastardly partnership with Kevin Owens, and together, they've transformed into two of the top heels on the entire roster.
In fact, you could even argue that Sami has surpassed Kevin, which could've been his intention all along. With the Rumble usually being a great opportunity for babyfaces to shine through, perhaps Zayn could be utilized as the underhanded heel who hides throughout the majority of the match before stealing a victory late in the day. It'd fit his character brilliantly, and you could probably use it as fuel for the eventual break-up between him and Owens.
