ESPN's Adam Schefter reports the 49ers have agreed to terms with Brandon Jacobs, formerly of the Giants. Jacobs is joining Randy Moss and former Giants teammate Mario Manningham as offensive additions in San Francisco. The 49ers will remain a run-dominant offense, with Jacobs perhaps handling the majority of the short-yardage and goal-line work, putting a dent in Frank Gore's fantasy value. Should Gore miss time, though, the more explosive Kendall Hunter would remain the back to own. Anthony Dixon appears to be the odd man out of the backfield picture.
