Defensive end Brandon Graham, who’s looking for a contract. Linebacker Nigel Bradham, who just signed one. Right tackle Lane Johnson, coming off his first — and possibly his last — Pro Bowl. Safety Malcolm Jenkins, who’s 30, and, suddenly, looks it. Even fourth-year middle linebacker Jordan Hicks, who runs the defense. He’s making a lot of tackles but he’s not making big plays. He’s looking for a contract, too.
