This debate has been seriously contested since James Harrison won the Defensive MVP in 2008 over DeMarcus Ware. The battle has raged on, and here we are three years later looking at the same thing. However, there is a new twist in 2011, another linebacker has emerged over the past three years that could be better than them all. His name is LaMarr Woodley, and he also plays for the Pittsburgh Steelers.
Before you write this off as a homer article, read the entire thing. I will be making cases for Ware, Woodley, Harrison and a select few other outside linebackers. At that point it is up to the Bleacher Report Community to decide which linebacker they want (or two that they want).
There are others to be mentioned too. Terrell Suggs is scary good. Clay Matthews has the NFL bloodlines and the pedigree.
