1. Strong up the middle. Sturdivant, who led the nation last year with 87 unassisted tackles, proved this spring he's capable of replacing Mark Paschal as starting middle linebacker. He moved from the outside to the middle, and that opened up a spot for sophomore Zach Brown.
2. New faces in the secodary. The departure of safety Trimane Goddard was a concern, but Da'Norris Searcy and Melvin Williams gave the staff confidence they can fill that role. Williams, a transfer from Coffeyville Community College, played primarily on special teams and as a reserve safety last year. Searcy continued the success he left off with in the Meineke Car Care Bowl as a fifth defensive back.
3. Best depth under Davis. As he enters his third season, Butch Davis has built the depth to the best it's been in recent years (with the exception of the offensive line). Even with the questions at receiver (see below) there will still be about eight players for the staff to choose from come fall.
1. Offensive line. The Heels still need to find some answers, specifically on right side. UNC has to replace three-year starters Garrett Reynolds and Calvin Darity. One thing that will help was the staff's decision to redshirt guard Jonathan Cooper, who was a quick, valuable member of the scout team last year and had a good spring.
2. Wide receiver. Considering UNC's leading career receiver is fullback Bobby Rome (31 receptions), the Tar Heels need somebody to catch the ball. That's a question we might not know the answer to until a few weeks into the season. Greg Little, Joshua Adams and Dwight Jones were the leading candidates this spring.
3. Not so special teams. The competition will continue this summer between Casey Barth and Jay Wooten. The bigger concern, though, is punter, where walk-on Grant Schallock was the winner by default this spring. C.J. Feagles will give him some competition this summer, but whoever wins, it will be his first collegiate kicks.
