The Rock is one of the most iconic figures in the history of wrestling, so naturally a victory over CM Punk for the WWE title at the Royal Rumble would be huge for the company.
Punk is in the midst of an incredible title run, and that's evidenced by his holding the title for over 400 days, which is the longest title run in the past 25 years.
This feud began way back in July of 2012 when the Brahma Bull announced on Raw's 1,000th episode that he would be challenging whoever was the champion at the 2013 Royal Rumble. At the end of that show, Punk attacked The Rock, effectively completing the champ's heel turn.
The Rock would eventually get revenge on the WWE champion after catching Punk with a Rock Bottom after The Rock's return during the first Raw of 2013. Punk would respond, however, and did so after receiving some help from The Shield, who attacked The Rock on the last Raw before the Rumble.
It set the stage for what will be a heated showdown between two of the best the WWE has to offer from both the past and present.
A victory for The Rock at Royal Rumble would be huge for a few reasons.
If The Rock were to unseat the current champion, it would be an epic ending to Punk's amazing tenure as WWE champion. Not only that, but Punk's title reign would end at the hands of one of the greatest ever to step in the ring, so there would be no shame in the loss at all, and Punk keeps his credibility.
Even if The Rock wins the title at the Royal Rumble pay-per-view, it doesn't guarantee he goes to WrestleMania as the champ. Instead, The Rock would have to remain the WWE champion through the Elimination Chamber, which is no certainty at all.
But let's say The Rock does hold onto the title at Elimination Chamber and goes to the main event at WrestleMania: His simple presence as a headliner in both of those events would attract a ton of attention from current and former die-hards of the WWE.
Since his last WWE title win in 2002, there's no doubt that some fans of that era have lost interest in wrestling.
The Rock's victory at the Royal Rumble and subsequent matches as the headliner for Elimination Chamber and WrestleMania could very well re-ignite those fans' passions, thus leading to a must-watch feeling for fans that otherwise wouldn't get involved.
Beyond that, The Rock has become more of a mainstream character thanks to his movie career, and while promoting a few upcoming movies he'll be in, The Rock would be doubling as a promotion for the WWE's upcoming events with the championship belt on his shoulder.
In the world of sports entertainment, ratings are king and The Rock would be bringing plenty of extra viewers with him into the main events to come should he be crowned champion and given a major role at WrestleMania.
With the Royal Rumble winner moving on to face the WWE champion at WrestleMania, The Rock's victory over Punk would lay the groundwork for a potentially unexpected and exciting matchup that no wrestling fan saw coming.
While wrestling fans might feel that The Rock doesn't deserve the WWE Championship because he hasn't been on the daily grind like most WWE Superstars are, they can't dispute the fact that The Rock winning the WWE title would be great for business.
