WWE WrestleMania 31: Superstars Favorited to Win Each Match

2) Roman Reigns (Brock Lesnar vs. Roman Reigns for the WWE World Heavyweight Championship)

Roman Reigns has been on a rapid rise since The Shield split up last summer. He has looked dominant in almost every appearance on WWE TV, won the Royal Rumble and even defeated fan favorite Daniel Bryan.

With WWE seemingly putting all of their eggs in on Reigns, it would be quite the surprise if he lost. This is despite the recent reports of Brock Lesnar being pushed to keep the WWE World Heavyweight Championship. However, if WWE feels that Reigns is not ready and are comfortable with Lesnar being off TV with the title, a loss for the former Shield man may happen.

The last factor into this is the fans. Reigns has not received the top Superstar reactions from the fans. His response is usually a mix of heavy boos and mild cheers. He has never had a loud ovation in his time as a singles competitor. If WWE takes this into consideration, Reigns will not win.
