Part of a series where I will compare the 2011 and 2015 defenses on paper. With every addition made, this season's defensive line could be the best in the Harbaugh era.
The 2011 line did not feature a dominant nose tackle. As a predominantly one gap scheme, it did not necessarily need a great one. Terrence Cody was the starter and Haloti Ngata saw some snaps at the position.
At the three technique, Cory Redding was a big - and at the same time overlooked - part of the line's success.
