Last season, one of the Achilles heels for the Lions was at the cornerback position. They clearly knew it; hence them drafting two corners to start the draft (Terrion Arnold, Ennis Rakestraw) and signing Carlton Davis in free agency. So far, that investment has paid off.
Arnold and Davis, in particular, are currently two of the better cornerbacks when it comes to playing in single coverage this season, according to a chart from Jrfortgang (@throwthedamball on Twitter). Both are playing single coverage at more than a 60% rate (the graph used a minimum of 100 coverage snaps) and both are above average (around -0.33) in terms of their separation grade, which used a scale from -2 to +2.
Davis is second on the team with eight passes defended while Arnold is fourth with five. Both are also among the top five on the team in tackles – Davis has 43, Arnold has 32.
Neither cornerback may be elite right now, but it’s much better play than what they got last season and it’s just one reason why the Lions are 7-1 and in the driver’s seat for home-field advantage in the NFC playoffs.
