But more than two months after Sherman signed a $57 million contract with $40 million guaranteed that made him the highest-paid cornerback in the league, Peterson and the Cardinals had this news late Tuesday night.
Peterson had been scheduled to make $2.88 million in base salary in 2014 with $10.08 million owed to him in 2015. His new extension now runs through the 2020 season.
Peterson is also the only first-round pick from the draft class of 2011 that has signed a contract extension.
For the record, CBSSports.com's Pete Prisco thinks Peterson is a better cornerback than Sherman.
Either way, the overall money (though not the average per year, which is still less than Sherman's deal) now gives Peterson an edge among the four generally considered to be among the best in the league: Sherman, Joe Haden and Darrelle Revis.
“That's going to go on the rest of our careers,” Peterson said Sunday, via the team website. “All four guys in the conversation … we all have different skill sets and all four of us have the ability to be the best in the league. The competition is real, I love it, and it will make all four of us play that much harder. I don't have anything against any of those guys.
“Do I feel I am the best cornerback? Absolutely. That answer is never going to change. But that conversation is always going to come up.”
