Criticize cornerback Nnamdi Asomugha all you want. The newest 49er knows it's coming, be it for his age, his uneven play the past two seasons, whatever. He has an answer at the ready. "There's a drive, there's a hunger inside of me that says, 'I know what I can do and I'm going to get it done,' " Asomugha said of his signing with the 49ers. "So, regardless of what others are saying or how others are feeling, I'm just going to make it happen."
