PFF Rankings: The top 25 cornerbacks through Week 7 of the 2020 NFL season15. Jalen Ramsey, Los Angeles Rams — 72.6Jalen Ramsey is a transformative talent for a defense — a physically imposing player at cornerback who can line up against the league’s freakiest receivers, allowing the rest of the Rams' secondary to worry about guys they can actually contend with. And Ramsey is on his way to the best PFF coverage grade since his incredible 2017 season in Jacksonville. Quarterbacks have targeted him 30 times this season for just 16 catches and 160 yards, and despite his incredibly physical play, he has been flagged only once this season.
23. Darious Williams, Los Angeles Rams — 70.1A surprise performer in the Rams' secondary, Darious Williams was impressive enough on limited snaps last year to fight his way into a bigger role and become a starter in 2020, kicking Troy Hill inside to the slot while he mans the other outside position alongside Jalen Ramsey. Williams boasts some huge plays on his tape this season, with two picks and three pass breakups. His diving interception to seal a win against the New York Giants back in Week 5 was one of the plays of the season so far by any defensive back.
