WrestleMania is traditionally about closing a narrative. The classic story is for a hero to overcome the odds to defeat a villain and take the treasure. This year WWE planned that hero to be Roman Reigns, with Brock Lesnar as the villain and the WWE Title as the treasure. But Mania isn't just about the closing of a journey. It can also serve as the basis for the start of the next big wrestling narrative. Take for example in 2011, when The Rock cost John Cena the WWE Championship. It served as the basis for a year long build to The Rock vs John Cena at WrestleMania 28. The end result? The highest grossing pay per view event in pro wrestling history. WWE should learn from that success and use Mania 31 to plant the seeds for WrestleMania 32. Next year's event will be in the 100,000 capacity Cowboys Stadium in Dallas, Texas. It will be the biggest Mania of all time and deserves a year long build to support its stature. There are several matches that WWE could be establishing for Mania 32 at this weekend's WrestleMania 31. Some have already been hinted at and mentioned by industry insiders. If any of these rumoured matches prove true, then we are in for an unmissable show next year!
