1. Significantly more depth at the skill positions. With the addition of Louisville transfer Anthony Allen, plus Marcus Wright and Embry Peeples, who played as true freshmen, and a few redshirt freshmen wide receivers, the Jackets have a lot of answers off the bench. Unlike last year, the Jackets now go three-deep at quarterback, as Tevin Washington, who redshirted last year, has shown this spring he can play.
2. Leadership on defense. Derrick Morgan and safety Morgan Burnett have clearly established themselves as leaders and arguably the top defenders on the roster. Burnett wasn't noticed as much last season because of his supporting cast, but that should change this fall. Both could be among the best defenders in the ACC this fall.
3. Unprecedented depth in the secondary. Jerrard Tarrant was cleared from his suspension, and redshirt freshman Kamaron Riley should give the secondary a boost. Plus, the Jackets have three returning starters in the secondary. Cooper Taylor and Rashaad Reid were impressive as true freshmen and now they've got legitimate experience.
1. The offensive line. It remains the biggest concern, in part because injuries slowed the progress this spring. Senior guard Cord Howard missed most of the spring, starting center Dan Voss missed all of the spring after shoulder surgery, Nick Claytor, who started at tackle last year after David Brown went down with an injury, missed all of spring and had back surgery, and the line was the weak link last year.
2. The kicking game. In the spring game, the kickers were 1 of 5 on field goals, including Blair, who was 0-for-3. There are a few walk-ons, but they are his only competition. Blair handled both kicking and punting duties last year and Chandler Anderson missed all of spring practice after bout with appendicitis.
3. Defensive changes. Because the staff knows it's going to be thin there, it tweaked the defense a little a bit and made one of linebacker positions a hybrid defensive back/linebacker position called the wolf. How the players grasp that will be a question, as will whether or not it will help take some pressure off the new players up front.
