Inarguably, the foundation of the Giants’ proficient offense is a forceful ground game.Spearheaded by a dominant offensive line, the Giants led the league in rushing last season, which followed the 2007-08 campaign in which the substantial contributions of running backs Brandon Jacobs, Derrick Ward and Ahmad Bradshaw were instrumental in their improbable journey that concluded with a Super Bowl title.But for the first two games of this season, the Giants’ ground assault had failed to launch. In Week 1 versus the Washington Redskins, the running backs totaled a pedestrian 106 yards followed by a mere 95 yards against the Dallas Cowboys in Week 2.Although they weren’t in crisis mode as the Giants came away with wins in both games, collectively, the offensive unit and coaches acknowledged that significant improvement was imperative.Facing the Tampa Bay Buccaneers on Sunday, Jacobs, Bradshaw and an eager O- line reestablished their bona fides by gashing the opposition for 226 yards. Bradshaw led the charge with 104 and Jacobs added 92 as the Giants moved to 3-0 with an overpowering 24-0 victory that dropped the Buccaneers to 0-3.”That was our game plan coming in,” Bradshaw said of the Giants’ focus on effectively running the football. “{Our objective} was…to get those linebackers flowing to get a lot of cutbacks”Jacobs added that despite the impressive showing there is still room for improvement. “It could have been a little better,” he assessed. “I think we’re working towards where we want to be… I thought the offensive line blocked well. They moved people out of the way.”The Giants’ backfield production should be augmented in the coming weeks with the return of Danny Ware, who has been inactive since sustaining a dislocated elbow on the opening kickoff against the Redskins. Ware became the third member of the Giants’ running back trio when Ward signed a free-agent contract with the Buccaneers in the offseason.
