Brandon Jacobs made good on a promise to repay a young fan who emptied out his piggy bank in an effort to keep the running back with the Giants. According to The Sacramento Bee, Jacobs, a free-agent signee of the 49ers, took 6-year-old Joseph Armento and his 4-year-old brother to Jump On In bounce house in Boonton, N.J., on Wednesday as a gesture of gratitude for Armento's desire to keep the running back.
