Welcome back to another season of "What You Might've Missed," a video segment in which I break down some X's and O's, focusing on the little things that can have a big impact on the game.

In this first edition of 2013, I examine the Packers' running attack over the first two weeks of the season. Specifically, the video takes a look at the Packers' blocking against two key run-defending linebackers, San Francisco's Patrick Willis and Washington's London Fletcher.
