#1 Samoa Joe

The new United States Champion, Samoa Joe, finally holds gold on the main roster.
Whilst the star-spangled strap may be the first time Joe has held gold on SmackDown, the Samoan Submission machine is a two-time NXT Champion, the first man to accomplish such a feat.

Even before then, Joe ruled in TNA Wrestling, holding their World title, whilst John Cena was making a name for himself in WWE.
Coming from two different worlds, a feud between the two would be epic, and a dream match many fans believed they would never see.
With the United States Title on the line (a title Cena has held on five occasions), expect these two veterans to give an absolutely amazing performance at the biggest show of them all, if the WWE are willing to pull the trigger.
