#3 Roman Reigns enters the Intercontinental Championship picture again
If someone had any doubts about Roman Reigns' wrestling ability, I think that after his performance at Survivor Series, their questions may have been put to bed for good. Roman Reigns was part of arguably the best match of the night when he took on members of Team RAW and Team NXT, and put Keith Lee on the map, elevating him significantly.
Even though Shinsuke Nakamura may be the WWE Intercontinental Champion at this point, the fact of the matter is that he is far lower on the totem pole than the top players on the SmackDown brand too, at this point. And at such a point Vince McMahon and WWE may call upon their resident big dog to elevate the man and the title.
I think that a feud between a babyface Roman Reigns, who has the crowd on his side these days and a heel Shinsuke Nakamura can be pure gold. Sami Zayn can be the mouthpiece for Shinsuke Nakamura, taking on Roman Reigns on the microphone (an area where he's improved significantly).
The matches would be great for sure if this feud were to happen at Survivor Series. And it would certainly improve the prestige of the WWE Intercontinental Championship by a huge margin.
