The Packers found a gem last year in second-round pick Casey Hayward. Hayward finished third in defensive rookie of the year after a stellar season in 2012, during which quarterbacks had a league-low 31.1 passer-rating against him.
Now in his first full season playing the nickel corner position, Hayward will have added responsibilities including additional blitzes. If his strong play continues he has a chance at making the Pro Bowl.
Not to be forgotten is Tramon Williams, still the Packers' best overall corner. Williams is called upon to cover the opposing teams' best receiver and usually does a good job of it. In a division with Calvin Johnson and Brandon Marshall, that's saying something.
The wildcard of the group is Sam Shields. Shields possesses elite speed but his instincts sometimes betray him. He needs to be more consistent, which he showed he was capable of throughout his 2010 rookie season.
Fourth corner Davon House showed potential last season but has looked less than exceptional so far this preseason. The Packers hope his spotty play has been an aberration and that House will start playing to his full potential.
This group could be a real strength for the Packers by the end of the season.
