#4 Sending the fans happy with a solid Iron-Man storyline to culminate the Royal Rumble

A.J. Styles' WWE debut at the Royal Rumble 2016 blew the roof off the place and while the management might have not expected that, the deafening reactions made them notice the Phenomenal One.
Since the former WWE Champion has always been compared to Shawn Michaels in his prime, Vince McMahon might have finally seen the spark in Styles'.
Judging by the way the recent Royal Rumble events have concluded, it seems like the company could be looking to end the drought and make the fans happy.
With Finn Balor ending up being the Iron Man in the previous Rumble, it would be a legitimate time for the company to bring the Phenomenal One into the frame and book him to win it all from the #1 spot.
It would be an incredible way to bring some rejuvenation to the money-making match and would be successful in cementing A.J. Styles as the man Vince McMahon wants as his guy.
