#1 Bill Goldberg

Though he knocked himself out against The Undertaker at WWE Super ShowDown by hitting his head on a ring-post and did not produce a good match, Goldberg redeemed himself at SummerSlam.
He took out Dolph Ziggler in a segment that lasted quite longer than the match itself but left a strong statement that evoked cheers from the crowd in Canada.

However, he can create such surprising segments from time to time and if utilized in the right way, can keep the audiences engaged for the upcoming years.
There is no doubt that he still gets the crowds chanting his name and is a fan favorite, along with the liking that he has for the kids, which makes him quite popular everywhere that he goes.
This could be a huge promotional factor for the company and they want to keep hold of him in the long run.
