James Shields has been one of the biggest bright spots on an improved Royals team this year. Not with guys like Williams, Shields, Hyde and Casey Hayward . But Shields is a master of the subtle arts, changing speeds, mixing pitch types and locations, and escaping some tough jams. That said, Whitt was quick to acknowledge that if one of his defenders proves unable to handle a certain matchup, say against Chicago’s Brandon Marshall or Detroit’s Calvin Johnson , then he would go back to matching coverage. Whitt said that decision was made well before Williams sustained his knee injury early in camp, and that plan will remain intact even after Williams returns, which the Packers hope is in time for the Sept. 8 opener at San Francisco.
