Welcome to the world of football—a world that is filled with very large egos.
Don't get me wrong, there are many classy football players out there that are the most genuine guys, but there's also some that have their heads filled with air—their egos are the size of their head.
Usually, the guys with the biggest egos are divas and prima-donnas, but some guys are simply flat out cocky and think that they're "all that."
In that spirit, here are the 33 biggest egos in NFL history.
I understand why Chris Johnson is holding out, as he's the league's most explosive running back and is making only around $2 million. However, you have got to have a pretty big ego to actually holdout.
I'm sorry, but CJ2K is still making $2 million and should be on the field right now proving that he's worth a pay raise, rather than being a fraud and holding out, making everyone believe that he's got a huge ego.
The second that Elvis Grbac was brought in to replace Trent Dilfer, he immediately starting to talk trash and prove to everyone that he's got one pretty big ego.
Grbac ended up being a fraud as 2001 was his last NFL season as he threw only 15 touchdowns and was intercepted 18 times.
Ricky Williams doesn't just have a big ego, but he's also a really odd guy.
Williams took a few years off from football to study the ancient Indian religion Ayurveda—a religion that involves a lot of marijuana usage.
Keenan McCardell spent most of his NFL career with the Jacksonville Jaguars playing alongside Jimmy Smith. Both wide receivers were extremely productive but were both polar opposites—Smith was quiet but McCardell was a talker.
In fact, McCardell is just another typical wide receiver diva.
Let me be honest, Jeremy Shockey thinks that he's a rock star, or at least, that's what it looks like.
Shockey had so much hype surrounding him when he entered the league as a member of the New York Giants, and from that point on, his ego never stopped growing.
If you don't think that Pacman Jones is full of himself, then there might be something wrong with you.
Pacman positively has one of the biggest egos in NFL history.
After winning the BCS National Championship with the University of Texas, Vince Young's ego grew bigger and bigger.
Ultimately, Young's ego was so big, that he pretty much hurt him while he was a starter with the Tennessee Titans.
Young was never able to prove to the Titans that he was good enough to be their starting quarterback.
During JaMarcus Russell's short lived NFL career, many questioned his work ethic and dedication to the game.
In my opinion, I believe that he was just so full of himself after his major success at LSU, that he felt like he never had to practice or work to get better.
How did that work out, JaMarcus?
Sometimes I can't stand Mercury Morris, but then again, I understand why he's so cocky.
Morris is a member of the only team in NFL history to complete an undefeated season, the 1972 Miami Dolphins.
Coming out of college, Matt Leinart never really understood what it meant to be an NFL quarterback.
Leinart never really showed that he was dedicated to the game and spent most of his time partying like he was still a frat boy back at USC.
Leinart's huge ego ultimately led him to have minimal success in the NFL as a starting quarterback.
Bill Romanowski knew he was a feared linebacker, which ultimately caused his ego to skyrocket.
Coming out of college, Michael Crabtree was drafted by the San Francisco 49ers in the first round of the 2009 draft—however, he felt like that he was worth millions and millions of guaranteed money.
In fact, Crabtree held out a chunk of his rookie season and actually considered holding out the entire season.
How big can your ego get? You're an unproven wide receiver out of college. Get over yourself.
Mike Vanderjagt should have just realized that he's only a kicker.
However, if you simply spoke with the guy, you'd probably think that he's Peyton Manning or something.
Vanderjagt will go down as one of the cockiest kickers in NFL history, as well as having a huge ego.
Larry Johnson had two great seasons during his career—2006 and 2007—but simply fell of the map ever since.
As Johnson emerged as an elite running back in the league, his ego got bigger and bigger, which ultimately was a key factor in his downfall in the league.
It's understandable that talented and star athletes will have huge egos but please explain how Freddie Mitchell thought he was any good?
Mitchell spent only four seasons in the NFL with the Philadelphia Eagles and caught only 90 passes for just five touchdowns.
When Jay Cutler was drafted by the Denver Broncos back in 2006, he came out of Vanderbilt with a huge ego, thinking that he had what it took to be great in the NFL.
Granted, Cutler's skill set is pretty impressive, but the way he handles himself needs to change, as his ego is far greater than his production on the field.
When you're the league's most dominating player for any length of time, it's almost expected that you're going to get a bit cocky and have a large ego.
Jim Brown was an elite running back back in the 1960s, and he loved every minute of it as he knew defenders feared him and he would simply try to hurt anyone who tackled him.
Albert Haynesworth has such a large ego that after he signed a $100 million contract with the Washington Redskins, he simply decided to stop caring about football.
Haynesworth has shown up to training camp out of shape, as if he doesn't care at all about the game and his job.
It is so obvious that Tony Romo is full of himself; it really is.
At times, you begin to question if Romo even cares about football, as he spends his entire offseason like a celebrity as he golfs, attends parties and has a very open love life with the media.
At times, Joe Horn's ego may have been a distraction, but you have got to admit that he was an entertaining wide receiver.
There is no question that Joe Namath has a very large ego. I mean, Broadway Joe was bold enough to guarantee a victory in Super Bowl III—and of course, Namath won the Jets the game.
Following the Super Bowl, his ego only got larger and larger.
Warren Sapp wasn't just a sack machine, he was almost like an entertainer.
He was very well aware that fans thought he was funny, so he kept up his antics as being one of the most feared defensive tackles of all time.
If you're the owner of "America's Team," wouldn't you be full of yourself and have a huge ego?
Jerry Jones definitely has a huge ego, and he thinks that he is the man.
Shawne "Lights Out" Merriman has one of the biggest egos of all time.
However, we all now know that he was a joke as he tested positive for steroids.
Everyone laugh at Shawne!
I'll give Rex Ryan credit, he's led the New York Jets to back-to-back AFC championship appearances, but his ego and big mouth are starting to get old.
There's no doubt that Ryan has a very large ego—he's the man in his world.
Randy Moss will go down as one of the greatest wide receivers of all time, but he was the center of his own universe.
Moss was all about Moss; that's how it was. All he cared about was himself, and it showed on the field.
No matter how much I dig Jim McMahon's mullet and sunglasses, he's got one of the biggest egos of all time.
After McMahon led the Chicago Bears to a Super Bowl victory back in 1985, his ego kept growing and growing.
McMahon was a decent quarterback, which gives him no reason to be as cocky as he was.
Let's face it: If you're a big-time wide receiver with a big mouth, then chances are you have a huge ego to go along with you.
Michael Irvinin was not only an elite receiver, but he played for "America's Team," the Dallas Cowboys, which definitely didn't help his ego.
Ray Lewis is one of the most feared defenders to ever play the game, and he knows it, which explains his huge ego.
Lewis is always yapping his mouth, but most of the time, he's backing it up.
I'm sorry, but if you change your last name to "Ochocinco," you should be labeled as one of the most egocentric human beings of all time.
Chad Johnson, now known as Chad Ochocinco, legally changed his name a few years back to 8-5, but in Spanish.
How stupid is that?
Deion Sanders will be remembered as one of the greatest playmakers and cover cornerbacks in NFL history, but he'll also be remembered along with his very large ego.
Sanders, nicknamed "Prime Time," knew he was good. So, he always strutted around thinking that he was "all that."
In my opinion, "Prime Time" is arguably the cockiest person to ever play the game.
Terrell Owens always has to be the center of attention—he's arguably the biggest wide receiver diva to ever play the game.
Owens has cried in press conferences, gotten into fights with his coach and quarterback and has even held a workout in his driveway just for the media to get a glimpse.
If it weren't for T.O.'s amazing abilities on the field, I am sure that many fans would have been fed up with his antics a while ago.
If you don't believe that Brett Favre has the biggest ego in NFL history, then there might be something seriously wrong with you.
Favre's ego is so astronomical that words are not able to describe it.
No. 4 has been in and out of retirement so many times as if he's just demanding attention. Even if you watch him in his press conferences, he's always talking about himself, never about the team. It's so clear that he's so self-absorbed.
At this point, there's only one person who's feeding Favre's ego, and it's himself.
Sorry, Brett, but you're old news.
