#3 Braun Strowman
Although Brock Lesnar is still owed his rematch after losing to Roman Reigns at SummerSlam, WWE's main goal with the finish at Hell in a cell could be a way to set up Strowman versus Lesnar down the line. In fact, with Lesnar throwing Reigns on Strowman to make the pin, it seems like Lesnar is most angry at Strowman.
Whether that results in a match between the two behemoths remains to be seen and would depend on Lesnar's interest before leaving for UFC, but think of what a win would do here for Strowman! Not only would it essentially take the sting out of him eventually losing out to Reigns for the Universal title, it gives him a win that not many other Superstars have on their resumes.
