Add 2013 holdovers James Hurst and Russell Bodine – both expected to be picked in the 2014 NFL Draft in May - to that list of NFL talents emerging from Fedora's initial front line in Chapel Hill.
"They were a special group," offensive line coach Chris Kapilovic said of his 2012 unit. "They worked extremely hard and they were good players. They grasped what we wanted to do and executed it, and in turn, broke a bunch of records."
Even with Hurst, a two-time first-team All-ACC left tackle, and Bodine serving as the centerpiece for last season's offensive line, the results were disconcerting early. UNC averaged 102.1 yards per game (2.8 yards per carry) through seven games before a mobile quarterback in Marquise Williams and a softer schedule nearly doubled that production (202.1 ypg) over the final six contests.
First-year starters Caleb Peterson at left guard and Jon Heck at right tackle –both red-shirt freshmen - joined sophomore right guard Landon Turner in developing through experience as the season went along. Reserve tackle John Ferranto and center Lucas Crowley also earned playing time last fall.
"There's nothing more valuable than experience for an offensive lineman," Kapilovic said. "It's not like you're throwing them a ball or he's running the ball and he's just got to be an athlete. They've got to understand schemes and the continuity and communication is very critical."
By the time that the offensive line started to mesh, Hurst and Bodine were saying their goodbyes. Such is life with the ever-changing rosters at the collegiate level.
"Now we're back to really starting over," Kapilovic said. "I have high expectations for Landon Turner. We don't have a senior in the room, but he's the oldest guy. Heck has a year under his belt and I expect him to continue to get better. This spring it's a bad situation that Caleb Peterson is not practicing because he needs that. And with Lucas Crowley, you think, ‘well, he played last year,' but he's still a freshman and he's got a long way to go."
Even Turner's hesitant to classify himself as the old guy in the bunch.
"We're definitely really young," Turner said. "I'm going to be a red-shirt junior next year and I've only started one full year. Two years ago I got about five games, I think. So we're young across the board, but I think we're in a really good spot because we've got nowhere to go but up. We've got a lot of potential to improve because we are so young."
The offensive line's inexperience was on display in Friday's scrimmage at Ardrey Kell High School in Charlotte. The first string allowed two sacks and committed a false start in the opening five plays, and while those errors decreased over the duration of the scrimmage, the defensive line won the battle handily.
Depth is also an issue. Without Peterson on hand this spring, a graduate assistant was forced to step in at second-team right guard during team run-throughs when Brad Henson missed a practice due to injury two weeks ago.
"It's going to take some time," Kapilovic said. "We've got to develop some guys that can give us some depth. There's just not many there right now."
With Crowley expected to fill Bodine's void at center and the three returning starters penciled into their spots from 2012, the primary question at hand is finding Hurst's replacement.
Kapilovic termed the left tackle position battle as "wide open" between Ferranto, red-shirt freshman R.J. Prince and true freshman Bentley Spain.
There's likely to be a combination of growing pains, learning curves and shared experiences once the season arrives in August. While the 2014 offensive line may not be ready to replicate the production of the 2012 unit, there's hope that level of play may return before long.
"We're going to be good in the future," Kapilovic said. "It's just trying to get them ready now. We have some good young talent here and it's just a matter of getting them ready sooner than later."
