By almost any metric you want to use, Grady Jarrett was impressive in his rookie season, especially for a part-time player joining the Falcons as a fifth rounder. In his second year, Jarrett's going to get a big boost in terms of his responsibilities, role, and playing time, and Atlanta's banking on that improving the defense.
You see, Jarrett's going to man the nose, which might seem like a weird thing for a 305 pounder to do until you realize that it effectively means that A) Jarrett will be asked to stop the run, which he does well, B) the Falcons don't need a hole-clogging nose on defense to be successful, particularly after adding run-stopping acumen elsewhere, and C) it means more playing time for one of the team's best young defenders.
The team being enamored with Jarrett is, in my humble opinion, great news for the defense. With Jonathan Babineaux getting up there in age, there's nobody else who has proven they can penetrate into the backfield on a consistent basis on the Falcons' interior, and Jarrett is already a damn fine run defender. I have no doubt he'll take this gig and run with it, and he and Ra'Shede Hageman will hopefully dominate up front. It would make a massive difference for the defense if they did, obviously.
