The Green Bay Packers are usually bystanders while other teams throw around millions in free agency. That's about to change.

NFL Media Insider Ian Rapoport said Wednesday on "NFL Total Access" that the Packers plan to take advantage of their nearly $30 million in cap space and acquire outside free agents, according to sources informed of the team's thinking.

Rapoport reported on NFL Network that the Packers could sign as many as five players, which would be the most for the team since 2006.

And who will Green Bay target? According to Rapoport, the team is committed to rebuilding its defense in a way that best suits the philosophy of defensive coordinator Dom Capers.

That means getting more athletic and versatile along the defensive line. A major goal is to improve their ability to blitz and get after the quarterback. Green Bay finished with 44 sacks last season, tied for eighth in the league.
