Brandon Jacobs is aware Giants fans will compare his productivity and versatility to that of retired Tiki Barber -- and the 6-4, 265-pounder must prove that he belongs somewhere other than the shadow of a former player half a foot shorter and 50 pounds lighter. He even said there "may be some question within the (Giants') organization" that he can be the team's true No. 1 running back. But Jacobs has spent the off-season preparing for this opportunity -- retooling his running style and workout regimen, embracing the motivation provided by the arrival of Droughns, and inspired by the birth of his first child. All while remaining ever-confident and defiant. "I don't give a damn what people say," Jacobs said. "I have talent, I can catch the ball, I can run with it. I don't have to run somebody over all the time. I actually am a running back."
