New York Giants defensive coordinator Perry Fewell has a familiar challenge Sunday: Trying to stop the New England Patriots. Fewell didn't have any luck trying it in five seasons as defensive chief with the Buffalo Bills from 2006 to 2010. He was the Bills' interim head coach the last six games of 2010 after Dick Jauron was fired. But he has a much better cast of players in New York. The audio clip begins with him giving the No. 2 key for his defense. No. 1 was simply to have fun and play loose.
