Shields' agent, Drew Rosenhaus, confirmed the four-year NFL veteran agreed to a four-year, $39 million deal with a $12.5 million signing bonus. Analysis: Undrafted out of Miami in 2010, Shields has emerged to combine with Tramon Williams to provide a solid corner tandem in Green Bay. He had 61 tackles with four interceptions and 16 passes defended last season. Pro Football Talk first reported the deal. This could be a busy offseason for the Packers, who are looking to add playmakers to a defense that slipped in the second half.
