Miami at Arizona: Dolphins DNA profile

Posted by ESPN.com's Mike Sando

The Cardinals can claim their first 2-0 start since 1991 by beating a reconfigured Dolphins team at University of Phoenix Stadium today. The Dolphins were one of the more active teams in free agency as they sought to recover from a 1-15 record last season.

Those interested in taking a closer look at the Dolphins can pick up a roided-out roster with enough information to last until kickoff, and then some. The Dolphins have only 20 of their own draft choices on the 53-man roster, tied for the fewest in the league and 6.2 fewer than average. That includes seven players drafted under current coach Tony Sparano, five drafted under previous coach Cam Cameron, six drafted under Nick Saban and two survivors from the Dave Wannstedt era (Yeremiah Bell and Vernon Carey).

The Dolphins' 53-man roster features 25 players drafted by other organizations, four more than any team in the league and 7.4 more than the league average.

Led by rookie No. 1 overall choice Jake Long at left tackle, the Dolphins are very young on offense. Only the Packers were younger on offense heading into games today. The Dolphins' defensive players are eighth-oldest on average.
