#2 AJ Styles is most likely to be the heel in his feud with Seth Rollins
This ongoing rivalry between Seth Rollins and AJ Styles might not call for a full-fledged heel as of right now, but we know that babyface vs. babyface feuds usually evolve up to a particular point after which the only possible direction left is for either of the two competitors to turn heel.
If last night's contract signing segment was any indication, then it seems like AJ Styles is most likely to fulfill the need for a heel persona in this particular scenario.
But until then, it will be interesting to see as to how far this feud can evolve with both men strictly under the confines of their babyface barriers.
Don't get me wrong, AJ Styles vs. Seth Rollins was the right direction to go for when it comes to the Universal Championship, but there will be a point where both of these characters will have to evolve to keep this feud interesting...
