Then why did they sign Moss and Manningham?
I think they will try (optimum word try) to balance the offense more this year, utilizing the RBs out of the backfield. Pathetic number of receptions out of the RBs (something like 35). Gore and Hunter are both good receivers and Harbaugh talked last year about how he wanted to get them out in space. Didn't happen though.
I just don't see Jacobs getting much work if he even makes the team. Gore had a solid year in 2011 and was injury free. Even when Harbaugh said he was limiting Gores touches due to an "injured ankle", Gore came out and said that wasn't true. It was a coaches decision, which I think had to do with trying to keep him fresh for the full season and playoffs, which is fine. He had 300 touches last year, which I think is perfect. I watched every game last year and didn't see much, if any dropoff from 3-4 years ago. They talk about Jacobs being the "short yardage" guy, but Gore is a tougher inside runner despite being 50 pounds lighter.
This signing just makes no sense to me, but will be interesting to watch.
