Eleven seniors are gone from that team, including its top two rushers in quarterback Austin Barker and tailback Brady Briggs, as well as its top two receivers in wideouts Daniel Musselman and Assa Deardorf.
The current roster features athletes who will be new to the varsity level, and that's something Lefebvre isn't necessarily biting his fingernails over.
"In some respects, we're so different offensively [than the previous coaching staff] that them having less experience is allowing them to transition into what we do a little quicker," he said. "Things went fairly well through our first few days of camp [last week], so we're pretty encouraged. But, there's going to be growing pains."
The previous coaching staff ran a spread offense out of the shotgun. Lefebvre will transition the Warriors into a more traditional triple option look, much like the ones seen in use by the service academies of college football.
Junior quarterback Jake White has worked with the first offense during summer drills. Multiple running backs may see significant workloads once the season starts, including seniors Damon Gipson, Keith Rouch and Todd Pocock.
Defensively, the Warriors of new won't look all that different. Lefebvre prefers a 3-4 or 5-2 look out of the front seven, something returners were used to lining up in under former coach Greg Miller, who left North Miami after last season to take the head coaching job at Manchester High School.
"With all the spread offenses you see today, you have to be flexible and be able to adjust to things," Lefebvre said. "There are some subtle differences and changes in terminology, but our defense won't be a wholesale philosophical change."
The Braves return their starting quarterback, leading rusher and leading receiver. Add that to a veteran offensive line that features four returning starters, and the crew in Bunker Hill feels like it can right the ship and return to the sunny side of .500 for the first time since 2004.
