The cornerback position was expected to be a strength for the Ravens this season, but they have gotten inconsistent performances from that group, Lardarius Webb and Corey Graham, in particular.

The struggles of those two cornerbacks continued in Sunday’s 24-18 loss to the Cleveland Browns, a game in which one-time third-string quarterback Jason Campbell threw for 262 yards and three touchdowns.

Webb was targeted eight times by Campbell, who completed five of his eight attempts for 71 yards when throwing into his coverage area, according to Pro Football Focus. Graham allowed five receptions for 84 yards and two touchdowns, including that highlight-reel score by wide-out Davone Bess, on six targets.

It gets worse for those two. Based on one signature stat from Pro Football Focus, few NFL cornerbacks have been picked on more than Webb and Graham this season.

Webb ranks 72nd among the 75 qualifying cornerbacks in yards allowed per snap in coverage. He has allowed an average of 1.83 yards every time he is asked to cover a receiver. Graham ranks 61st with an average of 1.51 yards per snap in coverage, according to Pro Football Focus.

Webb is not the only bigger-named cornerback to rank in the bottom 15 in this stat. Chicago's Charles Tillman, Dallas’ Morris Claiborne, Kansas City's Brandon Flowers and Pittsburgh's Ike Taylor are right there with him.

In case you are questioning the validity of this stat, Tampa Bay's Darrelle Revis, considered the NFL's best cornerback, ranks first at 0.40 yards per snap in coverage. Shutdown cornerbacks such as New England's Aqib Talib, Cleveland's Joe Haden, Seattle's Brandon Browner and Arizona's Patrick Peterson also rank in the top 15 in this category.

While Webb and Graham have struggled, Jimmy Smith has been a little better. The third-year corner has been beaten for an average of 1.29 yards per snap in coverage. That is not great, either, but it is closer to the middle of the pack.
