Green Bay Packers coach Mike McCarthy has refused to comment on speculation that there will be major changes to his coaching staff during the off-season.

At his year-end news conference on Wednesday, McCarthy reiterated that he was happy with his current staff, although he didn't specifically say that defensive coordinator Dom Capers would return to Wisconsin next season.

He told reporters: "Dom Capers is an outstanding football coach. No-one will be evaluated today. We'll go though this just like last year; you guys did this to me last year, asking about the coaches.

"I'm not going into this thing looking to make big changes, but I'll tell you one thing: when I go though this process, there's things you really like about your program. But as I said, I think Dom Capers is an outstanding football coach and I'm glad he's on our staff."

Green Bay's defensive unit came under criticism this season, which ended in defeat to the San Francisco 49ers last Sunday.
