With Marc Trestman's arrival at Halas Hall, the Bears have made many changes on their coaching staff.
The latest is a change at the strength and conditioning.
Rusty Jones, who had been the Bears' man at strength and conditioning for eight years, retired after eight years. Mike Clark has been hired in his place.
Clark was previously with the Chiefs and Seahawks in the same job. He worked under Mike Holmgren when Seattle went to the Super Bowl, and also worked for years at the collegiate level.
A change at strength and conditioning was warranted. An NFL team who has late season collapses two seasons in a row has to take a serious look at the way players are conditioned. The players put their bodies through a long, tough season, and they have to work now to stay healthy throughout.
