Every team has issues to address this offseason, and this week, we're taking a look at the most glaring holes for each ACC team and figuring out where they might find answers between now and the season opener.
Position to improve: Secondary
Why it was a problem: North Carolina had issues all over the defense in 2014, but it was particularly vulnerable to the pass. No Power 5 team in the country allowed more yards per attempt (8.5), only Baylor and Fresno State surrendered more plays of 25 yards or more through the air, and only six teams nationally allowed more passing touchdowns (31).
How it can be fixed: The Tar Heels' biggest issue in the secondary may have simply been youth. There was just one senior -- safety Tim Scott -- on the team's two-deep, and the Heels started three sophomores in the defensive backfield. UNC finished 88th in sack rate, too, and the lack of pressure up front certainly didn't help the secondary. The pass rush did show some improvement as the year went along, and emerging stars such as Nazair Jones and Dajaun Drennon should continue to make an impact in 2015. The big change, however, is the man calling the plays. UNC hired former Auburn coach Gene Chizik to take over the defense, and his hard-nosed style promises to translate to a more fundamentally-sound secondary.
Early 2015 outlook: North Carolina should improve defensively in 2015 if for no other reason than it would be virtually impossible to be any worse. Still, it's going to be an uphill battle. Young players are going to need to take big steps forward this offseason, and it remains to be seen how Chizik's personality and style will mesh with the players already on the roster. The Heels have two four-star DBs committed, but adding more youth to the mix isn't necessarily an ideal scenario. Moreover, Larry Fedora's offense moves at lightning speed, and the result of that was that no defense in the country spent more time on the field in 2014 than UNC. That's asking a lot of a group that is young, lacks depth and had fundamental flaws routinely exposed. How much of that can Chizik clean up in 2015? How much might Fedora try to adjust his offensive pace to account for some of those defensive shortcomings? How much can the youngsters grow in one offseason? We may not have those answers for quite a while.
