#4. Roman Reigns vs. The Rock as the main event of WrestleMania 39
Speaking of main-eventing WrestleMania, if this match happens, we know what spot on the card this one will take. But the key here is "if this match happens." We've been in this situation a couple of times now where they tried its best to lock Dwayne Johnson for its big shows, but due to the former WWE Champion's Hollywood commitments, nothing really came of those plans.
This year was no exception as The Rock was penciled in for a very long time to clash with his cousin Roman Reigns at The Show of Shows, only for plans to be scrapped once again due to the Brahma Bull's filming schedule.
Reportedly, WWE would try to go to this well one more time come WrestleMania 39, and rightfully so. Bringing arguably Hollywood's biggest draw to clash with its own biggest homegrown star is an opportunity WWE will never turn its back on, especially since the Showcase of The Immortals is in Hollywood next year.
It only helps that the two are real-life cousins who have both gone on record claiming how they, too, want this match.
As Universal Champion on Smackdown for well over 500 days now, Roman Reigns has comfortably been doing his career-best work. Coupled with Paul Heyman and his other real-life cousins, The Usos, his new "Head of the Table" gimmick has allowed Reigns to explore a new side of him that WWE has been reluctant to do for a very long time.
The company's commitment to presenting Reigns as its current biggest star, coupled with the champion's ability to draw inspiration from his rich wrestling lineage, has been one of the only few highlights in the company of late.
The way this story has been built so far - with both Jey and Jimmy Uso at some point standing up to Reigns for their family's honor - it is only a matter of time before a certain "Great One" takes exception to Reigns' claim as the family's alpha.
#3 The Undertaker gets inducted into WWE Hall of Fame
In WWE terms, you either retire at the perfect time (see Shawn Michaels), or you keep clinging onto your past glory until it becomes abundantly clear that you cannot do this anymore.
The Undertaker should have retired a long time ago - arguably at WrestleMania 30 when his streak got broken. Instead, The Deadman kept going for a few more years, looking worse off with each passing match.
His matches with the likes of Roman Reigns, DX, and Goldberg all died slow, methodical deaths in front of the live crowd; however, the 56-year old was still able to redeem himself towards the end thanks to his 'Boneyard Match' against AJ Styles in the main event of WrestleMania 36 night 1.
As it stands, The Undertaker has gone on record claiming that he's "officially retired" and even started appearing in the media as the man behind the character. Perhaps it was that last good match he was looking to go out with.
But as much as this retirement was essential, it still leaves a deep void in any WrestleMania card - a show The Undertaker has appeared in a record 25 times over his illustrious career.
Should WWE really consider breaking attendance and viewing records for the 39th installment of its annual extravaganza, it would need to incorporate The Undertaker on the show in some form or the other.
Now, if this was 2020, the most creative way to do this would've been to have a Demon Balor vs. The Fiend match to figuratively crown The Undertaker's successor.
WWE could've even brought in Taker to acknowledge the winner in some sort of a dark "passing of the torch" moment.
Vince managed to botch both of Taker's successors in the same year, and a Hall of Fame induction for the veteran would be the next best alternative. WWE can really take various creative routes when it comes to The Undertaker's Hall of Fame induction.
