Defensive coordinator Wade Phillips is optimistic he can do just that.
"He's really at the peak of his career right now," Phillips said. "He's got a lot of good things going for him. He's going to be a great addition because he's going to make plays. He's led his team in tackles, in interceptions. He's done all of those things. He's experienced."
The Chargers have experienced a shaky pass defense for years. Last season it finished 28th in the league with only 10 interceptions.
McCree, who came over from the Panthers, is looking to change that. And he looks for his change of cities to produce a championship, something the Panthers nearly accomplished last year before losing in the NFC Championship Game to the Seahawks.
"The Chargers are a playoff-bound team," said McCree, of an organization that has made the playoffs once in the past 10 seasons. "They have a great opportunity to win the Super Bowl. I think they represent a winning organization. They have all the pieces in place. I'm happy, thrilled and honored that they also had interest in me to come in and help this organization win a championship."
McCree, who had three interceptions last season, has the versatility that allows him to play free or strong safety. At strong safety, he would have to supplant Terrence Kiel; at free safety, Bhawoh Jue.
"It doesn't matter which spot I play," McCree said. "The coaching staff has told me that I'm going to have to compete. I'm looking forward to that competition. Whatever they need me to do, I'm willing to do it. I'm happy to do it. I just want to help this team win a championship and I think we'll be able to do that."
What McCree should be able to do is reach a comfort level fairly quickly, in that he sees familiar faces in secondary coach Brian Stewart and old teammate Keenan McCardell. Stewart was on the Texans' staff when McCree played there and McCree and McCardell were on the Jaguars together.
"Brian is a great defensive backs coach," McCree said. "He teaches things very well and makes things very easy to understand. I'm excited about getting to play with him."
