Facing The Undertaker at WrestleMania is a big deal.
Getting that key slot on the card might actually be bigger than a world title match at this point.
Every year that he goes undefeated, the more prestigious the opportunity comes.
So far, it doesn't seem that it's been fully decided on who he will fight at the biggest show of the year.
With so few genuine stars on the roster, there aren't a lot of people to choose from.
As good as guys like Wade Barrett and Antonio Cesaro are, no fan would believe for a second that they had any chance to end the streak.
If WWE gets creative, though, there are some dark-horse candidates who could give The Dead Man an intriguing match up.
Here are seven wrestlers worthy to challenge The Undertaker at WrestleMania.
Over The Undertaker's career, he has helped establish talent like Steve Austin and The Rock while they were in their prime.
His last four WrestleMania matches, though, have been devoted to Michaels and HHH. Two guys near the end of their careers.
If WWE wanted to give a rub to some younger talent, there may be no better choice than The Shield.
Many fans would argue that Roman Reigns, Dean Ambrose and Seth Rollins are the most intriguing part of WWE these days.
Ambrose is especially someone that could be a big player in the company in the future.
To make a big statement, the WWE could have them take on Undertaker in a tag match at WrestleMania.
Also, if Taker wasn't completely healthy, it would also help lighten the load on his body.
Ideally, it would be Kane joining up with his brother one last time to make the match even more meaningful.
Of course, Undertaker shouldn't lose the match, but having him come out of seclusion to take on The Shield would make them seem like a big deal.
WWE seems to have dropped the ball with Ryback.
He's an unstoppable character who has been stopped too many times lately.
Instead of going all-out with him, they've had him lose to Punk on three separate occasions.
Right now, it sounds like WWE may be building up to a Big Show/Ryback showdown at Mania.
That match isn't sure to excite many, especially since Big Show's title reign has ended.
Besides, we've already seen Cena give Show the Attitude Adjustment at WrestleMania, so it's not like it would be a "first time ever" moment to lift the giant.
With Rock and Brock wrestling at Mania, Ryback's match will be the fourth most prestigious match on the show at best.
What could get people talking is if he called out The Dead Man.
If Ryback gave Undertaker a good fight with some close near falls, it could potentially get people to believe the streak was in jeopardy.
The match ending in a mutual-respect handshake could also help out the man that WWE so desperately wants to get over.
I realize the thought of Goldberg vs. Undertaker sounds ridiculous, but hear me out for a minute.
Over the past 20 years, the two biggest streaks in wrestling (Punk's title reign currently being the third) have been Undertaker's 20-0 at WrestleMania and Goldberg's 173-0 record in WCW.
Of course, Taker's streak is held in much higher regard, but in it's time, Goldberg's run was insanely popular.
To this day fans still chant his name when Ryback is on TV.
Fans went crazy over the thought of seeing Sting and Undertaker lock up a couple years ago. But with the Stinger currently under contract to TNA, they could reach out to another big star from their old rival.
At 46, Goldberg is getting up there in years. But he still looks the part, and with a few months to train could look like a formidable opponent.
He also sounds like he's itching to have one final match.
Undertaker wouldn't have to worry about living up to his Triple H and Michaels matches. Facing Goldberg wouldn't have to have a five-star classic.
It would purely be a spectacle match. It wouldn't even have to go on very long. They would just need to have a hard-hitting brawl to get the crowd excited.
The finish would never be in doubt, but the visual of seeing these two lock up for the first and only time ever would be memorable.
It seemed that WWE was teasing us with a potential Undertaker vs. Brock match a couple of years ago.
After Lesnar lost his Heavyweight Championship at UFC 121, he conveniently walked right by Undertaker.
The two engaged in a brief staredown.
Nothing ever came of it, but that doesn't mean WWE couldn't revisit the tension between them.
It's too bad that Lesnar has already lost in WWE. An undefeated monster would be a much more intriguing opponent for Taker.
Still, the two of them could potentially have a classic match. They already have a rich history dating back to Lesnar's first run in the company.
Lesnar and Cena had a great showdown at Extreme Rules, and Taker showed at last Mania that he still has it.
Undertaker has been adding a variety of MMA submissions to his repertoire over the years, which could make the match stand out. It would contain some hard-hitting realism that no one else could compete with.
Besides, pairing Brock up with Taker can keep us away from a HHH/Lesnar repeat.
I get the feeling that a lot of fans had their fill of Rock vs. Cena last year.
It doesn't seem that people are clamoring for a rematch.
What could be more interesting would be a showdown between The Phenom and The Great One.
Sure, the two have faced off in the past, but it's been over a decade. They've gone on such different career paths that a showdown between them would still be a dream match.
Undertaker was somehow never challenged by The Rock, Steve Austin or Mick Foley at a WrestleMania. This would be a chance for him to add one of the Attitude Era's top stars to his tally.
With Rock and Undertaker on such limited schedules, there could be potential for the match itself to be a letdown.
But regardless, the aura of two of the all-time greats facing off one last time would be epic.
As of right now, this is looking like the most likely match. That doesn't mean WWE couldn't change their mind at any moment, though.
If Undertaker is concerned about finding an opponent to give him a good match at Mania, then Punk should be high on his list.
Hopefully if they go this route, Punk will still hold the WWE Title.
Punk's title reign has become a big deal, and Taker's streak is a huge deal. Having them both on the line would be a tremendous opportunity to deliver a great story.
In Punk's never-ending quest for respect, he could target the most respected wrestler in WWE history.
Visually, it might seem like a mismatch.
The two have faced off before, and Taker always came out on top.
Punk's mic work has risen to new levels over the past couple years, though, and he could leave fans salivating at the thought of Taker getting his hands on him.
With the incredible amount of work Punk has done the past year, he deserves a shot at ending the streak perhaps more than anyone else.
WWE would be wise to save this match for WrestleMania 30, but there's never a sure thing in wrestling.
Due to a variety of circumstances, sometimes fans are deprived of a huge showdown.
Even though they competed in the same era, we never had a Hogan vs. Austin match, or saw Rock and HBK go at it. Both could have done huge buys.
Taker has a lot of mileage on his body, and Cena too is spending more time on the sidelines than in the past.
There's only so many more chances that WWE will have for these two be healthy, and in good enough shape to fight each other.
If the company really got to it quick, Cena vs. Undertaker could be the biggest match they have.
What would make things so dramatic is that Cena is possibly the only guy on the entire roster that fans would believe could defeat Undertaker at WrestleMania.
It would also be the perfect chance for him to turn heel.
Even his most ardent supporters probably wouldn't want to see The Streak end, and Cena cheating to accomplish that goal would get him instant nuclear heat.
Don't expect it to happen this year, but let's hope these two face off before Undertaker calls it a career.
