For months I've been wondering how the Green Bay Packers went from a very mediocre defense that couldn't stop the run to being dominant. Same players basically, so what did they do? I found an article on ESPN that explains how Clay Mathews was asked to play inside line backer and how successful they've been.

I'm not one to comprehend all the Xs and Os but like the results. Can the Browns fix their defense using this philosophy? Please explain those that know. Thanks!
