As we head into spring football, there will be some pretty big names missing from the rosters -- Clemson needs to replace its starting quarterback, safety and running back, Duke lost the ACC's leading tackler, Virginia lost its leading receiver and rusher, BC lost its starting defensive tackles, Georgia Tech needs to replace three of its four starting defensive linemen, and UNC needs to replace all of its top receivers -- just to name a few. There will also be plenty of replacements within coaching staffs.
Here are the five biggest shoes to fill in the ACC this spring:
Virginia Tech cornerback Victor "Macho" Harris -- Not only will the Hokies lose one of their top defenders, they'll also lose a true leader. Last season, Harris had 14 passes defended and six interceptions -- including two returned for touchdowns -- and two forced fumbles. One option is to move Stephan Virgil to the other side like the staff did when Brandon Flowers left. Another is to let a few players battle it out. Rashad Carmichael started the game Harris missed due to injury.
Florida State defensive end Everette Brown -- He led the league in sacks and tackles for loss. Brown's season sack total was 13.5 and his career sack total was 23. Markus White, who was Brown's backup in 2008, earned his first sack against Clemson, and is the front-runner to succeed Brown. Kevin McNeil also has experience at the end position.
Wake Forest linebacker Aaron Curry -- The Butkus Award winner finished the regular season with a team-leading 101 tackles and 15 tackles for loss. Curry finished his career with 332 tackles and a school-record 278 career interception return yards. Jonathan Jones was Curry's backup last season and has some experience there.
UNC receiver Hakeem Nicks -- Nicks set UNC single-season records in 2008 for receiving yards (1,222) and touchdowns (12). In just three seasons, Nicks established 14 school records at UNC, including career receptions (181), career receiving yards (2,580) and career touchdowns (21). The staff recruited several receivers who are expected to compete for time this fall, but Joshua Adams, who enrolled in January, could have a slight edge because he'll be practicing this spring. Sophomore Dwight Jones should also be in the mix, along with Todd Harrelson and Rashad Mason.
Boston College coach Jeff Jagodzinski -- He took the Eagles to back-to-back ACC title games, including 2008, when little was expected of the Eagles in their first season without Matt Ryan. Jagodzinski left Boston College with a 20-8 record (11-3 in 2007, 9-5 in 2008). Former defensive coordinator Frank Spaziani will be in his first season as a head coach.
