Crazy Thought of the Day: It's time for John Cena vs. Undertaker at WrestleMania

WrestleMania season is here and with the Royal Rumble only a few weeks away, it's time to really nail down who will be challenging who in each match on the card. There's a combination of six wrestlers who will occupy the top three slots and they are, in no particular order:

Brock Lesnar
John Cena
CM Punk
The Rock
Triple H
Undertaker

The rumor mill tells us by the time the card is set, it will look like this:

Brock Lesnar vs. Triple H
The Rock vs. John Cena
Undertaker vs. CM Punk

I have no qualms with Lesnar and Triple H in a rematch of their SummerSlam encounter, mostly because I know that if Triple H wants it, he'll get it and that's that. But I'm most definitely not a fan of the other two matches.

So here's the "Crazy Thought of the Day" -- switch Cena and Punk around.

Yes, it's finally time to put together John Cena vs. Undertaker at WrestleMania 29.

After what we saw on Monday Night Raw this week, there's no doubting a Rock vs. Punk match will draw a ton of eyeballs. Having it at the Royal Rumble will prove as much, not to mention give us a sneak peek at the level of match the two can put together. It gives them some time to build chemistry.

However, because of last year's WrestleMania, Cena should want to be involved in some way or another. He was defeated by The Rock at that show, clean in the middle of the ring. He's a competitor and he wants a rematch, "Once in a Lifetime" marketing last year be damned.

So maybe Cena tries to get himself involved in the match at the Royal Rumble pay-per-view. Maybe he tries to help Rock win the WWE championship so he can go on to face him for it at WrestleMania 29.

Maybe just as he's picking up Punk to hit the Attitude Adjustment and everyone is wondering what the hell is going on, the lights go out. The gong hits and Undertaker slowly makes his way to the ring. Cena lets Punk slide off his shoulders, frozen in bewilderment at what is happening before him. Mesmerized by the surprise presence of "The Deadman," he simply looks on as the demon from Death Valley stares him down.

Then, the inevitable look to the WrestleMania banner. Then, the throat slash.

It's on.

Cena has beaten them all. He always manages to overcome the odds, no matter how stacked they are. Yes, he lost to The Rock last year but he could get that win back on a Raw show sometime soon enough. No one would bat an eye at that either because that's how it works with Cena.

He always wins.

But at WrestleMania, so does Undertaker.

There may not be a single wrestler left on Earth who could challenge 'Taker for his WrestleMania Streak and create even a shadow of a doubt that he might lose.

Except John Cena.

Book it.
