Multiple changes for Chiefs in Haley's 3rd year

Andy Studebaker squirms out of his tight-fitting, sweat-stained practice jersey and tosses it onto a pile. At 6-3, 250, Kansas City's fourth-year linebacker looks as solid as those cars his family used to make. With the retirement of Mike Vrabel, Studebaker is the No. 1 candidate to become a starting outside linebacker for the Kansas City Chiefs, a job he's been training for the past two seasons. On the offensive line, second-year man Jon Asamoah is probably going to replace five-time Pro Bowl guard Brian Waters. Those are just two of the biggest changes coming to KC this year as the Chiefs launch their defense of the AFC West title.
