The Undertaker has enjoyed a professional wrestling career like no other, and even in his mid-50s, the future Hall of Famer is still going strong.

Undertaker's place in WWE immortality is secured. Nobody will be able to emphasize enough just how much he truly changed the sports entertainment industry, especially in WWE.

At this stage of his career, the only real question is a complex one: Is The Undertaker the greatest wrestler to grace the ring, or does that title belong to someone else? There are plenty of reasons to argue for and against it. Let's analyze five reasons for each.

10 GOAT: Putting Other Talents Over

There are plenty of wrestling legends who refused to put younger talents over, and they know who they are.

But The Undertaker never displayed any selfishness whatsoever when it came to helping other superstars -- especially in the later stages of his career. He willingly allowed Brock Lesnar to end his WrestleMania streak, and 'Taker also did his part in getting Roman Reigns over by losing to him at WrestleMania 33.

To be the GOAT, you have to do what's asked of you, and Undertaker did that without hesitation.

9 Not The GOAT: Lack Of Championship Success

Superstars like John Cena and Ric Flair have "GOAT" cases especially because they are 16-time World Champions. Despite spending 30 years in this business, The Phenom doesn't come anywhere close to matching up to other legends in championships.

For example, he's not even part of the Grand Slam Champion club, and he only captured seven World Championships. Fair or not, Undertaker's lack of title success somewhat affects his status as the GOAT.

8 GOAT: Leadership

The greatest athletes of all time always displayed some form of leadership. They motivated their teammates to be better every night, and they set a gold standard for everyone to follow.

Well, The Undertaker did just that -- keeping together a WWE locker room that was plagued by plenty of drama and real-life tension. Backstage, Undertaker ran a thing called "Wrestlers Court," where he would hear problems between WWE talents.

He simply took it upon himself to deal with all the backstage problems, because Undertaker didn't have time for it. No wonder he was so respected and admired by all his peers and employers.

7 Not The GOAT: In-Ring Work Is Good, Not Great

Many of the all-time greats in WWE were extremely limited when it came to in-ring performance. This includes Hulk Hogan and Goldberg, among many others.

Now, The Undertaker was never a terrible wrestler by any means. But when you compare his performances to other legends like Shawn Michaels, The Rock Kurt Angle and 'Macho Man' Randy Savage? There's quite a gap there.

Undertaker was far from the absolute best when it came to in-ring work.

6 GOAT: Longevity

Unbelievable! 30 years after his WWE debut, and The Undertaker is still standing tall as a big-time money draw for the company. What else can we say about this guy?

There aren't many wrestlers who performed for as long as The Undertaker. Sure, he's been used more in a part-time role for the better part of the last 10 years, but his legendary status hasn't declined in the slightest.

Find me the other GOATS of wrestling. Most of them didn't come anywhere close to competing for 30 strong years like this man.

5 Not The GOAT: Match Predictability

Sure, the main event stars rarely lose their matches. But with Undertaker, the problem was that you knew he was seldom going to drop a match cleanly -- especially during the 21st century.

Up until his loss to Brock Lesnar, you knew the other opponents had no shot of defeating Undertaker at WrestleMania. And when it came to a marquee championship match, you knew Undertaker was always going to a) win or b) lose in unclean fashion.

There was simply too much predictability in his matches, and in some ways, that has to affect his status as being the goat. A huge part of wrestling is "expect the unexpected," after all.

4 GOAT: The Streak

What more can we say that hasn't been said already?

For 21 consecutive matches, The Undertaker conquered his opponents (some bigger, some faster, some smarter) on "The Grandest Stage of Them All." His streak didn't end until a national champion and former UFC star answered the bell at WrestleMania XXX.

Just think about all the legends that Undertaker defeated during his streak: Triple H, Ric Flair, Kane, Batista, Randy Orton, and Shawn Michaels. You'll simply never see a streak like that in professional wrestling ever again.

3 Not The GOAT: Dragging On Too Long

There are too many cases where WWE legends simply don't know when to call it quits. Shawn Michaels stayed true to his word for eight and a half years before coming back for one more match in 2018, which ruined his whole retirement stipulation.

Other legends like Flair and Hogan didn't know when it was time to hang up the wrestling boots. And now, the soon-to-be 56-year-old Undertaker is going through that same stage.

His in-ring performance has declined significantly in recent years. There have been nonstop rumors about his retirement for several years, and Undertaker's career is simply dragging on when it's not necessary. He should think about retiring on a high note, rather than drag it on for the sake of being "loyal" to Vince McMahon.

2 GOAT: Reinventing Himself

At the end of the day, nobody changed up their gimmick time and time again -- while succeeding on every single occasion -- like The Undertaker. If there's one firm case to make that he's the king of all kings, look no further than his ability to reinvent himself.

It all started with the "Western Mortician" character before he introduced subsequent characters such as The Deadman, The Phenom, and The Last Outlaw. And no matter what gimmick he portrayed, The Undertaker shined through as a top-tier superstar.

That, folks, is why The Undertaker has strengthened his case as the greatest of them all.

1 Not The GOAT: The Competition

At the end of the day, competition stands in The Undertaker's way of asserting himself as the true GOAT of professional wrestling.

Shouldn't the GOAT moniker go to Hulk Hogan, who turned the WWE into a global phenomenon during the '80s? What about Ric Flair, who brought more charisma and style than anybody else? Steve Austin and The Rock saved WWE from losing the war with WCW. What about those two? Doesn't John Cena deserve a mention too? What about The Heartbreak Kid, by far the greatest in-ring performer ever?

Throw all of those names in together, and does Undertaker deserve the "GOAT" title over them? This is really the biggest thing that stands in his way of being the greatest wrestler to ever live.
