#3. John Cena took the fall to Roman Reigns as he doesn’t have time for too many matches in WWE
John Cena returned for a blockbuster match against Roman Reigns at WWE SummerSlam. Cena has never defeated Reigns one-on-one in televised matches, and the record stood post-SummerSlam.
It was one of Cena’s biggest opportunities to become a 17-time World Champion in WWE. However, Cena has only returned for a few weeks and will not be able to stick around for long. This is one of the key reasons why Reigns was allowed to retain at SummerSlam.
WWE creative would have likely been tempted to award the Universal Championship to Cena had he come back for a longer run in the company. However, a short run with the title could have hurt Reigns' credibility and the title’s value.
