3. Karlos Dansby (Cardinals to Dolphins)
Karlos Dansby is Miami's second entrant on the new faces in new places category. The Dolphins acquired Dansby early in free agency. As coach Tony Sporano said at camp, "Whenever we played against Karlos he was around the ball." In the last three years, Dansby has averaged 108 tackles, three sacks, six passes defended, two interceptions and two forced fumbles. Dansby solidifies a defense that gave up 349 yards a game last year, and he brings the experience of winning division titles and earning a Super Bowl appearance in Arizona.
