Katie Hoff is switching coaches. From the Washington Post:
Swimmer Katie Hoff has changed coaches after a disappointing Olympics in which the six-time world champion failed to win a gold medal in a half dozen events.
Hoff is working with Michael Phelps's coach, Bob Bowman, who has returned to her North Baltimore Aquatic Club after four years at the University of Michigan. Hoff trained with Paul Yetter since before she qualified for the 2004 Olympics as a 15-year-old.
