Fantasy analysis: Peterson has the skill set to contribute immediately. Arizona was a touchdown machine on defense last year, posting twice as many scores as the next closest team in the league.
Peterson may not start initially, but he should be no worse than the nickel back. As an IDP choice, look elsewhere. Arizona's defensive team unit is a low-end No. 1 because of their opportunistic play, but you cannot count on them returning 10 turnovers for scores again.
