Cable spoke on Wednesday at the Raiders' first full day of camp. The team has meetings scheduled all day long and will begin practice on Thursday.
Campbell will open with the first string. Cable says he is going that direction because Bruce Gradkowski missed the past three months with a torn pectoral muscle.
Cable said after acquiring Campbell from Washington during the draft in April that there will be a competition at quarterback.
