Kansas City Chiefs
Key unrestricted free agents: Safety Jon McGraw and tackle Adrian Jones. The young Chiefs could stand to lose both players.
Key restricted free agents: Center Rudy Niswanger and safety Jarrad Page. While the restricted free agent market is often slow, both of these players could be intriguing.
Dream free agent match: Quarterback Matt Cassel. If the Patriots do not place the franchise tag on Cassel, new Chiefs boss Scott Pioli would likely attempt to bring in the blossoming star to be the centerpiece of his new team.
