For the most part, the Chiefs are pretty comfortable with their defense when fully healthy, as they believe they have the right mix of young players and veterans, not to mention a lot of talent. However, they do have a major need for a nose tackle. Kelly Gregg manned the position in 2011, but as a free agent at age 35, he is likely to either retire or move on to a different team. We hear that finding his replacement will be a top priority this offseason, either through free agency or the draft. The only other nose tackle on the roster with any experience is Amon Gordon, who had two starts last season, and he is considered to be more of a role player than a starter. Jerrell Powe, a sixth-round draft pick in ’11, was called a "swing and a miss" by a team insider, as Powe never rounded into playing shape and was active for only one game.
