5 ways WWE could book John Cena following WrestleMania 

#4. Samoa Joe vs. John Cena

Samoa Joe and John Cena could open a feud

Samoa Joe was rumored to be entering a feud with John Cena and one of the ways that this feud could finally get underway would be if Cena shows up on RAW tonight and challenges The Undertaker to another match, but instead, it's Samoa Joe who makes his return and puts Cena in his place.

Joe and Cena's careers have run side by side over the past few years with Cena becoming the face of WWE and Joe making waves in TNA. This would be one of the showdowns that the WWE Universe have been waiting for and it would establish Joe as "the right hand of destruction" that he once was.
