#4: The Destroyer does what he does the best

The Royal Rumble was a great show in many aspects, but what it failed to provide was a single surprise entrant, apart from Tye Dillinger at 10, which was a one-off appearance. Fans waiting for Balor, Joe and Nakamura had to settle for Roman Reigns at number 30, which led to bullsh*t chants.
Seth Rollins had to miss the Rumble due to Stephanie McMahon's problems with the Kingslayer, which led to Rollins calling out Triple H every week. He even invaded NXT Takeover event in search of the WWE COO. Triple H finally came to RAW the night after Rumble to answer Rollins, but he didn't come alone.
Look who just shut down all of Tony Khan's critics! More HERE.
Samoa Joe's sneak attack on Rollins and further destruction, which led to Rollins suffering a legitimate injury; which became a huge talking point. It proved WWE's willingness to make Joe a legit top superstar in WWE, and considering the year he had, they were correct.
