#3. Roman Reigns is still the main event
Say what you will about Roman Reigns. Love him or hate him, the fact of the matter is that there's no full-time superstar who gets the reactions that he does. What he proved at Fastlane was that despite having no real stakes on the line, he's still the main event of the show.
Sure, he's 100% not headlining WrestleMania for the fifth year in a row, but even so, when he's out there, it feels important. Post-WrestleMania, you can fully expect Roman Reigns to start regularly featuring in PPV main events.
Even if it takes a month or two, his rise back to the top is only inevitable. It's going to be interesting to see what direction they take for him. It's rumoured that he's facing Baron Corbin at WrestleMania, and while that's not a great match, it's most likely filler to heat Reigns up after the biggest season of the year.
