John Cena kicked off SmackDown and gave us a recap of what happened last week up to the point where Roman Reigns accepted Finn Balor's challenge. He said that Roman proved he was scared of Cena by refusing his proposal for SummerSlam."... @WWERomanReigns is just a scared little kid."#SmackDown @JohnCena @HeymanHustle pic.twitter.com/Kk4RqEYsde— WWE (@WWE) July 31, 2021Cena said the WWE Universe was done caring about Roman; which is why he needed to change his gimmick so often, unlike himself.Baron Corbin showed up and said that he was down bad and asked John for help. Cena asked the audience if he should help and the crowd provided a mixed response.
