Defensive line isn’t a vitally important position for the Packers, but they still have to have them. And even with the acquisition of Ricky Jean Francois, the Packers may be in the market for another run stuffer.

But finding a big lineman to battle in the trenches isn’t as easy as it may sound. The Packers have a specific set of physical attributes they look for, and it’ll shape their draft decisions in this area.

What’s the best round to select a defensive lineman?

Defensive linemen are the defense’s version of wide receivers: you need a bunch of them, and there’s a steep drop-off after the first and second rounds.

What rounds have the Packers drafted defensive linemen?

Highest pick: B.J. Raji, 2009
To play a 3-4 defense, a team needs a space eating nose tackle. Ted Thompson made sure the Packers had one when he drafted Raji ninth overall in 2009.

Biggest disappointment: Justin Harrell, 2007
Thompson tried to fortify the Packers’ defense to give Brett Favre one last chance in 2007 when he picked Harrell. Instead, Harrell spent more time on injured reserve.

Best value: Mike Daniels, 2012
Mike Daniels plays every snap like he’s been personally offended by the player across from him, and he’s parlayed that attitude into great success; once a fourth round pick, he’s now one of the NFL’s top defensive linemen.

Who might the Packers draft on the defensive line?

Eddie Vanderdoes in particular is of note, especially given the Packers’ proclivity for PAC-12 picks, and Nazair Jones also brings a lot to the table. In the late rounds, Charles Walker shows promise inside.
