McCree is the top defensive back they had hoped to bring in when free agency began.
The former Carolina Panther played at the league minimum a year ago and snagged three interceptions and recorded 95 tackles after replacing Thomas Davis in the starting lineup.
McCree has 11 interceptions over his last four years and has been a starter in just two of those seasons.
He is a staple of the type of player the Chargers prefer to bring in - a player on the rise that can come in and immediately start.
At 5-foot-11, 202-pounds, McCree reads and reacts to the ball well and has displayed good closing speed.
General manager A.J. Smith made it a priority to bring in more competition to the defensive backfield and McCree is the first step. Generally, when the Bolts target a player, they make it clear that he is the top priority and do what they have to make sure he does not leave town without being named a Charger.
Drew Brees hit the open market and several teams are expected to show interest. The Minnesota Vikings and Miami Dolphins lead the charge but the New Orleans Saints are also interested. New head coach Sean Peyton, a former quarterbacks coach, is believed to think highly of Brees. The Vikings, though, are reportedly very interested if they can wrap up the Daunte Culpepper trade quickly.
