The Cardinals' cornerback had the sixth-best defensive Pro Football Focus grade in the NFL this week, finishing with a 91.7. Peterson, who guarded Cleveland star wide receiver Odell Beckham, Jr. for much of the contest, allowed five receptions for 38 yards on 12 targets, with an interception and three forced incompletions.
When Baker Mayfield targeted Peterson, he had a passer rating of only 15.3, which was easily Peterson's best showing of the season. Peterson feels like he is finally rounding into form physically after missing the first six weeks of the season due to suspension.
"My legs are finally coming back to me," he said. "Coach Buddy (Morris) told me a superior athlete that misses one week it almost like missing two weeks. Now this is technically like my tenth week getting back in the swing of things. Body is starting to come back around, and I'm feeling good."
