Having The Rock win the WWE title at the 2013 Royal Rumble would increase the animosity between him and CM Punk.
Having Rock back is great, but the novelty will probably wear off a little bit after the Royal Rumble. Fans will have had the opportunity to see him in the ring again and will have heard him on the mic for over a month.
In the buildup to last year's WrestleMania, the longer The Rock was on television, the more you could hear the crowd reaction start to wane ever so slightly.
Right now, the rivalry just doesn't seem unique. In a way, The Rock feels like just another wrestler trying to get the belt off Punk.
Sure he's The Rock and the biggest star of anybody in the company right now, but there isn't anything to set his feud with Punk apart from almost every other one that's involved a guy who's challenged the champ in the last 400-plus days.
Going into WrestleMania XXVIII, the feud between The Rock and John Cena had a bigger, more personal feel to it.
There were legacies on the line. If Rock won, his star would only grow. If Cena won, he would rightfully take his place among the likes of Stone Cold Steve Austin, Hulk Hogan, The Rock, Bret Hart, Shawn Michaels, etc.
In addition, there were some points where fans were left wondering if Cena and The Rock actually did hate each other in real life. Their promos had their cute parts tailored to the younger audience, but both guys had cutting words for the other.
That's what The Rock and Punk are missing right now.
Last year, The Rock talked about how the adult fans hate and don't respect Cena. That's a relevant point because Cena's the biggest face in the company, so his express purpose is to be the good guy that everybody loves.
Then Cena comes back with how The Rock needs to write his promos on his wrist because he can't remember them.
Those were serious bombs dished out.
Compare that to the present where The Rock talks about how the people abandoned CM Punk. He either doesn't understand or doesn't care that the people cheered Punk for months after his heel turn. More importantly, Punk doesn't care what the fans think of him, so the point has no validity.
If this is how the feud is going to be the rest of the way, it will fail to take full advantage of the potential in the rivalry.
The Rock winning the title would help to add a different angle to a rivalry that really needs freshened up.
