During the New York Giants' practice Thursday morning, Brandon Jacobs made eye contact with Tiki Barber and held up a single finger. It wasn't one of those "We're No. 1" things. It was more a plea from the young backup halfback to the 31-year-old star to stay for one more season instead of retiring, has Barber has indicated he is likely to do at the end of the season. "I am trying to get him back for one more," Jacobs said. "I'm doing the same thing they are trying to do upstairs. Give me one more. If he does decide to walk away from the game, I know what I have to do. The job is mine to lose."
