5. Roman Reigns
The next big thing in wrestling increasingly appears to by the 'heavy' of The Shield. For Reigns to rise above two such accomplished complete packages such as Ambrose and Rollins is admirable. This story works both ways too. If Reigns stays heel, he's the cocky upstart with strength on his side who wants his piece of history. Also, there's the little moment of spearing Taker through a table earlier this year. If he turns face, it's the young fighter looking for confirmation from one of the biggest names in the business. Reigns, similar to Lesnar, has strength and speed on his side and this would make for an interesting dynamic in the ring. Also, the intensity of both men would make for a story to be told with very little mic work and, in the over-talked world of the WWE, a story told through stare-downs and signature moves would be far more interesting for the audience. Also, word has always been that if anyone would break the streak it would be a younger wrestler and Reigns fits this bill which would make for an unpredictable main event.
