I’ve been scratching my head since I read Jim Harbaugh’s remarks about Brandon Jacobs from his Monday presser. Asked if Jacobs was still a member of the team, Harbaugh took refuge behind the Fifth Amendment. Curious. The Fifth, as far as I understand it, is about avoiding self-incrimination. But Harbaugh was not protecting himself from self-incrimination. He simply didn’t want to deliver the goods. There’s a difference, unless Harbaugh really was protecting himself from self-incrimination. That would make quite a story. One other thing, in his whole career as a 49er — not much of a career — Jacobs never got as much ink as after he got suspended and was essentially no longer a Niner.
