49ers: Perrish Cox continues to impress
Cox, who had been released by the 49ers during the middle of last season (and again late by Seattle) before being brought back by San Francisco in the postseason, has stepped in admirably at left cornerback after Tramaine Brock injured his toe in the first quarter of the 49ers season opener in Dallas.
Since moving into the starting lineup, Cox has earned a +5.8 overall grade which ranks fifth among cornerbacks, and his 28.6 passer rating allowed is tops in the league.
Cox has made game-clinching interceptions in back-to-back weeks, and his three picks are tied for the league lead. In addition, he is allowing just a 46.7% catch rate when targeted.
With Brock scheduled to return to health in the next few weeks, the 49ers will have a decision to make in the secondary.
