WWE SummerSlam is this Sunday from the Barclays Center in Brooklyn. It is the highlight of what is going to be a fantastic weekend for WWE, with three straight nights sold out at the 15,000 capacity arena. Business is booming around the show, but will it be a critical success? In the build-up, it has been less exciting than last year's Cena versus Lesnar event. In fairness to WWE, the promotional job this year was always going to be hard one, with three of their top headliners barely featuring on television. Cena was out with a broken nose, while Lesnar and Taker were unavailable. The one highlight of the build was the Lesnar and Taker brawl, but that was way back on the July 20 Raw. Still, a show like SummerSlam sells itself. Lesnar versus The Undertaker is the kind of main event that will do well with the masses, while Cena and Rollins for the WWE / US titles is likely to be the wrestling match of the evening. The well stocked undercard features Kevin Owens versus Cesaro, which also looks to be very promising. It is a big night for WWE, their WrestleMania in August, and the following are the expected results.
