Consider, if you will, the components that fall directly under the term aggression. What is aggression and, perhaps more importantly, how does it show itself on a football field?
Aggression can take many forms, including but not limited to that of a dirty player. While there are dirty players on this list, not every aggressive player can be considered dirty.
Sometimes aggression presents itself in the form of a hard-hitting assassin or a guy with an unyielding motor. Aggressive players may even find their outlet through psychological means.

The 10 men who make up this list share a commonality. They are the most aggressive football players the NFL currently has to offer. For one reason or another, when these guys line up in front of you, expect a long, miserable day that will likely conclude with an even more painful night in bed.
