Of the many changes a new season brings to USC, one of the more significant is the restructuring of its offensive line.
The Trojans were young and lacked depth across the front five in 2013, two traits that were readily apparent at times. USC surrendered 34 sacks on the season, 21st-most in the nation, and the unit's growing pains led to some offensive struggles in the first half of the campaign.
The improvement of both quarterback Cody Kessler and the team as a whole coincided with improved offensive line play. However, the early departure of center Marcus Martin for the NFL draft and a rash of injuries challenged the group in the initial workouts of 2014.
Various offensive linemen have used the vacancies this spring to develop, which should manifest in the 2014 season as some sorely needed depth.
USC will return the injured among its offensive line ranks, including Jordan Simmons, Nico Falah and 2013 starter Aundrey Walker, and that's good news. With head coach Steve Sarkisian introducing a hurry-up, no-huddle offensive scheme, the Trojans will need as many game-ready contributors as they can muster.
