5 Things CM Punk failed to do in WWE 

Better known as "The Best In The World, CM Punk had a phenomenal career with WWE. He made his way into the company after leaving Ring Of Honor in 2005.

Punk made his main roster debut with ECW. Using his straight-edge persona, he became one of the top stars on the brand and soon made his way to the RAW.

From there, Punk rose to the pinnacle of his career. He won multiple titles and even set a record for holding the WWE Championship for 434 days. Now, Punk achieved so many things during his decade-long career with WWE. However, there are still a few things left that "The Best In The World" failed to do in WWE.

So, let's see today what accomplishments CM Punk didn't achieve and the reason for them also. Without further ado, let's get started.

#5 CM Punk failed to win the United States Title

Why didn't CM Punk win the United States Title

Before CM Punk walked out of WWE, he held almost every title there was in the company. From singles to tag team titles, The Best In The World laid his hands on every belt except one -- the United States Championship. This title has been held by legends, such as Harly Race, Ricky Steamboat, Rick Flair, and many others.

Punk has been compared to all of these great names, but he never succeeded in winning the U.S. Championship they all did. Now one might wonder how's that even possible when Punk worked with WWE for over a decade? But there's a very good reason as to why Punk never once fought for or held this prestigious title.

When Punk was an uprising contender, he spent most of his time on RAW.

At the time, the United States Championship was exclusive to SmackDown. By the time Punk became a fixture on the blue brand, he attained the status of a main event star.

So there was no reason any more to put the United States Championship, a mid-card title, on the shoulders of Punk as it would've done no favor to his rising career. Because of this, Punk not only missed out on a run as the U.S. Champion, he also missed out on earning the distinction of a Grand Slam Champion.

#4 CM Punk failed to win King of the Ring

Why didn't CM Punk win the King of the Ring tournament?

One of the biggest tournaments that have been taking place in WWE for a very long time is King Of The Ring. Most of this tournament's winners have seen their careers go from the bottom to the top. A few names to have benefitted the most are Ted DiBiase, Stone Cold "Steve Austin", and Booker T.

Now during CM Punk's decade-long WWE stint, a total of three King Of The Ring tournaments took place but he partook in only one of them. In 2008, Punk was one of the eight participants in the KOTR tournament.

He first defeated one half of The Hardy Brothers, Matt Hardy, in the quarterfinals and then scored a pinfall over Chris Jericho to advance into the finals. However, he was there defeated by William Regal who eluded the title of KOTR from Punk.

Nonetheless, the next KOTR tournament took place two years later. While Punk had a good chance to win the title of KOTR, he had been suffering from an injury that year, which is why he had to skip the tournament.

#3 CM Punk failed to defeat Triple H

Why didn't CM Punk defeat Triple H?

In 2011, CM Punk was chasing the WWE Championship but was failing at his every attempt. He claimed (kayfabe) it was because of Triple H who was using his strong position in the company to keep him away from the championship. But Triple H disagreed and a feud between the two men quickly ignited.

Punk and Triple H had their first match at the Night Of Champions. While Punk initially thought he would get a chance to score a win over Triple H that would help his career get a push, surprisingly, the opposite happened. At the pay-per-view, Triple H defeated Punk in humiliating fashion and the latter couldn't digest it.

He questioned "The Cerebral Assassin" as to why he didn't put him over when it would've been best for the business. However, Punk didn't find an answer that could make him understand it and decided to go a separate route from Triple H.

A few years later, Punk got another opportunity to face Triple H at WrestleMania 30, but he didn't jump on it. Instead, he left WWE in a controversial fashion. To this day, Triple H remains one of the stars Punk failed to defeat one-on-one in WWE.

#2 CM Punk failed to win a Royal Rumble match

Why didn't CM Punk win a Royal Rumble match?

Throughout his time with WWE, CM Punk participated in a total of five Royal Rumble matches but he was never the last man standing. For example, in his debut Rumble match, Punk represented ECW. He lasted over 20-minutes and eliminated only one star before getting eliminated by Chavo Guerrero.

"The Best In The World" took part in Rumble matches for the next few years, but he was merely a favorite. The time however came for Punk when he almost grabbed a Rumble victory. In 2011, Punk entered Rumble as the 21st entrant.

He eliminated a total of seven stars before "The Face That Runs The Place" John Cena threw him off the top rope. Surprisingly, it was a blessing in disguise for Punk as he started the biggest feud of his career with Cena a few days later.

Nonetheless, Punk again came close to winning Rumble in 2014. He even made it into the top four but was thrown over the top rope by Kane. If only Punk had won, he could have then achieved the very thing that's mentioned next on this list.

#1 CM Punk never the main event WrestleMania

Why didn't CM Punk ever main event WrestleMania?

Fighting in the main event of WrestleMania is one of the things CM Punk failed to do. What's ironic about this is Punk wanted the main event more than anything in WWE. During his eight-year-long stint, a total of eight WrestleMania took place.

Though he wasn't ready the first few years after he made his way into WWE, during his last three years in the company, he was one of the biggest stars. He had momentum and fans loved his "The Best in The World" character.

He could've closed at least one of those three WrestleMania's, but he wasn't given the chance. Surprisingly, John Cena got the opportunity to main event all those three WrestleManias. Punk should've at least got the main event spot at WM 29 since he was scheduled to face The Undertaker, who had his streak on the line.

However, the officials passed that opportunity on to The Franchise Player. Finally, John Cena came out of the main event picture in 2014. However, the officials still weren't very ready to let Punk main event WM. Well, "The Best In The World" had enough. Due to this and a few other reasons he parted ways with WWE.
