Although a team's success isn't measured by the toughness of its logo, a little intimidation never hurt anybody.
While logos have changed and evolved over time, the "scare tactic" has never gone away.
Although not every team has a daunting, overpowering logo to scare off visitors, there are those that are just that much more intimidating than the rest.
Let's take a look at the 10 most intimidating logos in the NFL.
With their light blond or fire-red hair, the Vikings tore through continental Europe in the ninth century.
The people they conquered referred to them as "savages" because of their unpredictability, their incomprehensible languages, and their preference to destroy churches and monasteries during their conquest.
With a heavily Scandinavian population, the Viking was the perfect logo for Minnesota's football team.
Who isn't afraid of a 6'4'', 220-pound man with long blond hair wielding an axe?
Rams use their long, curled horns as a means for intimidation when it comes to proving dominance over another male.
They run at each other at an average of 20 mph while having 30-pound horns on their head.
Not only is that impressive, it's a headache.
Luckily, the Rams have an intimidating logo, because their football team hasn't done anything to intimidate anybody since 2004.
With its angry scowl and long, curved beak, the Seahawk is one of the most intimidating bird logos in the NFL.
The dark blue primary with the light blue contrast draws attention the angry, green eyes that makes this one of the most unique logos in the NFL.
Not to mention that it's known as a "fish-eating raptor."
With a big, angry cat like the Panther, this logo should be higher up on the list.
However, something about light blue doesn't scare me. While the sharp teeth and the narrow eyes are on full display to draw intimidation, the shade of blue just kills it for me.
Bagheera from The Jungle Book was a panther, and he was as friendly as can be; except for when it came to Ka the snake.
Like the seahawk, the eagle is a predator in the wild.
The City of Brotherly Love has a mean logo, and the darker green is much more intimidating then the lighter green they team used to have.
This logo just looks angry, probably because the Jacksonville Jaguars are sure to be the laughingstock of the NFL this season.
In terms of intimidation, the multiple, sharp teeth give of vibes of anger and masculinity.
Perhaps it's frustrated at the fact that the team has 25 wins in the last four seasons.
The logo's intimidating, but the team is not.
With a fiery-orange background, the Denver Broncos have one of the most unique logos in the league.
The blue and orange color scheme separates the Broncos from every team in the NFL with the exception of the Chicago Bears.
As time has progressed, the Broncos logo has become more intimidating.
A skull and crossbones, a red and black color scheme, and a football. Just screams "unnerving" and "awesome" at the same time.
It's not one of those "Jack Sparrow" pirates, either. The Tampa Bay Buccaneers have a very daunting logo on the side of their helmets.
Pirates take everything they can get their hands on. Whether it's through torture or murder, they were without a doubt the most intimidating people to hit the sea in the 18th century.
A black primary and an angry bird with glaring red eyes gives the Baltimore Ravens the second-most intimidating logo on the list.
Ravens have a dark, mysterious aura about them, and Edgar Allan Poe brought them to life when he wrote "The Raven" in 1845.
Not only are Ravens some of the smartest of all birds, their fearful, shrieking caw makes their prey shiver in fear.
Very similar to their football team.
While the Oakland Raiders haven't made the postseason in nearly a decade, their logo remains the most intimidating in the NFL.
The Raiders have had the same logo since 1963, and the ambiance their shield has created can't be matched by any other team in the league.
The primary black color, along with the dark image the one-eyed pirate portrays gives off a fearful perception to opponents.
With the logo comes the persona of winning at any cost, and having a history of trying to do so.
The late Al Davis crafted the Raiders' image to a tee.
