Some positions and some players are simply destined to never get any column inches. 3-4 nose tackles get very little in the way of love from the media and it takes a very special player–who tends to be of a more disruptive nature–to get anything in the way of ink. Combine that with sharing a defensive line with two players like Darnell Dockett and Calais Campbell, two disruptive upfield atypical 3-4 defensive ends, and you know that you’re unlikely to get much of a look in for any credit. Further that by playing as a backup and it is almost a dead certainty that your performances will be overlooked.
That is the fate that befell our Secret Superstar for the Arizona Cardinals in his rookie season of 2011. The pairing of Dockett and Campbell are known league-wide for being forces in getting upfield, but their run defense is lacking and, without the aid of other players doing some grunt work, is destined to be the Achilles Heel of a defense. That is the work that David Carter quietly put in during his debut season in the NFL, backing up two players that he outperformed this season. A second-year nose tackle was our Secret Superstar for Arizona last season but hopefully Carter will fare a little better than Dan Williams did in 2011.
