Raiders head coach Tom Cable has remained noncommittal when asked about how he’ll deploy is three running backs, now that all are reasonably healthy. While Cable has not named a starter for the last two games, Michael Bush expects to be on the field when the game begins and figures the amount of work he gets will correspond to his production. “I know I’ll be starting and I’ve just got to make the best of my opportunities,” Bush said. “That’s the only thing I can do right now.”
