30-year-old Peterson is leaving the Cardinals of Arizona as one of the best cornerbacks in franchise history.
He went to eight Pro Bowls in a row, beginning his rookie year in 2011 and ending in 2019 – when he was ineligible for banning six games for violating the NFL’s performance-enhancing drug policy. Peterson is a three-time all-pro.
Peterson’s positional flexibility is a welcome perk for the Vikings Secondary, which had two rookie starters between 2020 Jeff Gladney, who queued the slot for 529 snapshots last season, and Cameron Dantzler, a selection from the third round that allowed the lowest passer-by rating of all rookie corners in the second half of the season (41.9 from week 11-17).
With questions about health and the future of the first round in 2018 Mike HughesPeterson, whose fifth-year option is likely to be turned down by Minnesota, is giving the Vikings stability in secondary school after a season of seven pass separations, his most since 2013. His three interceptions were his largest since 2016.
Peterson has been widely regarded as one of the best cornerbacks of his career, known for his ability to defend the top recipients of the opposing offense one-on-one on an island. He started all 128 games in the first eight seasons of his career before his suspension. In 2020 he was named to the 2010-2019 All Decade Team by the Pro Football Hall of Fame.
Peterson played all 16 games last season and had 61 tackles and three interceptions. He has 28 interceptions in his career.
He joined the independent agency after a five-year extension signed in 2014. Peterson requested a deal during Arizona’s dire 3:13 season under former coach Steve Wilks in October 2018 but later apologized. However, reports continued to circulate of a broken relationship between Peterson and the Cardinals’ front office, casting doubt on his future with the franchise after his contract expired in March.
