The 49ers' initial preseason depth chart lists Michael Crabtree as the team's only starting wide receiver. Listed opposite Crabtree is "Randy Moss or Mario Manningham or Ted Ginn." It's business as usual from coach Jim Harbaugh, who has made a habit of both talking up the mercurial Crabtree during his two years in San Francisco, and insisting he has five candidates to be the No. 1 receiver in camp. Moss is the favorite to open the year as a starter opposite Crabtree.
