Th NFL is a quarterback-driven league. At the mercy of the league's best pass throwers is the cornerback. The job of the cornerback is to try and limit the damage inflicted by the opposing team's most important offensive player.
A good pair of cornerbacks will cover up a lot of sins committed by a defense. Teams that can't rely on impact players in the front seven of their defense desperately need good cornerback play to avoid being torched by the Rodgers and Brees quality QBs of the league.
Conversely, a bad corner is a QBs best friend. If a corner simply cannot stick with a given receiver, a competent veteran QB will recognize that situation and exploit it over and over again.
Click through the slideshow for five cornerbacks that opposing QBs love to target.
It seems like every week Captain Munnerlyn is in the background of a long TD pass on SportsCenter. Despite the fact that Munnerlyn has started all 13 games so far, he has only logged five passes defensed.
Captain has been a central figure in one of the worst secondaries in the NFL. Opposing QBs practically lick their chops when they see the Panthers on the schedule. Munnerlyn has become a fairly sure tackler, but much of that can be attributed to all the chances he gets after his man catches the ball on him.
Cedric Griffin had a particularly bad day today—and that's saying something given the season he has had. After Titus Young burned him deep, Leslie Frazier made the drastic move to bench the veteran corner.
When the coach of a team that has as many flaws as the Vikings singles you out for benching, it's probably time to start thinking about your next job. While every team in the NFL would be more than happy to face off with the Vikings, QBs have taken a special liking to Cedric Griffin.
Quentin Jammer used to be a cornerback that made the most of all the passes that came his way. Jammer has 18 career interceptions, but at the age of 32, he has lost the ability to make those big plays happen.
The Chargers have stumbled through most of this season, giving up big plays and failing to win the turnover battle. Jammer has been a large part of the problem on both sides, as he has been beaten with regularity and has failed to produce any INTs.
Dunta Robinson is another veteran cornerback who has lost a step in coverage and fails to do much more than tackle his man several yards down field after the damage has already been done.
Truthfully, Robinson has always been somewhat overrated. He is a solid run-support corner, but he almost never makes the big plays that would make a QB think twice before targeting him.
The Falcons, who picked Robinson up just two years ago, are probably checking the receipt to see what the return policy is on Mr. Robinson.
Ronde Barber has had a remarkable career as a cornerback. Almost no one makes it to 36 years of age at that position.
While Barber is a heck of an athlete, it's about time for him to follow in Tiki's footsteps and retire. Barber has been a favorite whipping boy for opposing QBs for years now, as shown by his meager passes defensed numbers as compared to his tackling stats.
Barber has been a rock of consistency for the Bucs, but the time has come for him to move on.
