#3 Joe calls out Cena
Last year, John Cena did the unthinkable, calling out The Undertaker for a WrestleMania match in one of the most scathing promos in WWE history. He literally destroyed The Undertaker's mystique onscreen. The first promo especially would go down as something both Cena and The Undertaker will revisit from time to time. Well, it's time karma hits John Cena.

Samoa Joe is one of the best talkers in the business. He has already shown how good he is on the microphone, most notably in his promos against AJ Styles. He brutally and mercilessly attacked AJ Styles a number of times, and each time he did it, it was intense and amazing.
Hence, it's definitely a good idea to have him constantly call out John Cena, and tear the Champ apart verbally, leading up to their rumored match at WrestleMania 35.
The promos could be made intense and personal, considering the history between them right from their time together at UPW. It'd be interesting if this match happens, and how it happens.
