49ers running backs coach Tom Rathman confirmed that he views Brandon Jacobs exclusively as an inside runner. Rathman hinted that Jacobs too often tries to tiptoe to the edge. "He has to understand who he is as a player. We need him to pack it up inside and run over guys and be physical as a ball carrier. If we want to ... run outside, we'll put somebody else in." Jacobs will try to earn a short-yardage role at training camp.
