Jacobs signed a one-year deal with San Francisco in late March after spending seven seasons with the New York Giants. He won two Super Bowls and beat the 49ers 20-17 in overtime of the NFC championship game at Candlestick Park on Jan. 22.
In June, Jacobs received a letter from a 6-year-old Giants fan named Joseph that included $3.36 in cash from the boy's piggy bank — the child's contribution to try to keep Jacobs in New York with the reigning Super Bowl champions. The boy's mother, Julie Armento, wrote that she explained to her son that the Giants didn't have enough money to bring Jacobs back on a new contract, thus prompting her son's adorable gesture.
Jacobs then connected with Joe before the season when he returned home to New Jersey.
The 30-year-old Jacobs ran for 571 yards and seven touchdowns last season as a backup to Ahmad Bradshaw. He is the fourth-leading rusher in franchise history with 4,849 yards, but saw his role diminish with the emergence of Bradshaw.
Now, he is behind three-time Pro Bowler Frank Gore and Kendall Hunter among others. Jacobs knew full well he was joining a busy backfield.
"I come to work every day, I work hard, and that's just about all I can do," Jacobs said. "That's it."
