#4 Sami Zayn
Now, if the WWE really and truly want to use Bobby Roode to his fullest capabilities, he needs to be a heel. And, if they do decide to go down that route, there's a readily made opponent for him waiting in the wings and his name is Sami Zayn. The two men could work some real magic in a program together.
The Underdog from the Underground is always over with the crowd and will actually inspire audience members to hate Roode rather than cheer him on as they are wont to do with most heels these days. And, lest we forget, Zayn is one of the most gifted in-ring performers on the roster today.
His speed and quickness against Roode's methodical and powerful style would create a superb combination and the two Canadians can have one of the feuds of the year if done right.
