7 Biggest Potential Culprits In WrestleMania 31 Sucking

3. Brock Lesnar

Lesnar is a great wrestler, there's no doubt about that. However, he needs to turn in the performance of a lifetime if the main event of WreslteMania 31 is to prove its doubters wrong. His recent contract extension will have eased fears about his motivation levels, and its now up to Brock to prove it once and for all. Roman Reigns' inexperience has been widely speculated upon, giving the champ a great deal of responsibility. Whether he's retaining the belt or not, Lesnar has to take a leading role and allow the younger star to shine. Both men have a great look and considerable ability, so there's no reason they can't prove fans wrong and deliver a compelling spectacle. However, Brock's utter stinker of a match with Goldberg still lingers in the memory despite taking place over a decade ago. He's risen to the occasion previously in his career; doing so again on Sunday is crucial.
