There is really only one major question regarding the USC offense heading into the 2020 season.
Sure, there are plenty of lesser curiosities -- how will the Trojans divide carries with all of their top four running backs available? What young receivers will emerge with Michael Pittman off to the NFL? Can Kedon Slovis stay healthy so the thin QB depth is not tested? Etc.
But in terms of pivotal position uncertainty that could significantly swing the Trojans' offensive outlook, that spotlight is really on the offensive line.
Not only did USC lose both starting tackles from last season -- LT Austin Jackson as a first-round NFL draft pick, and RT Drew Richmond to exhausted eligibility -- but the roster depth on the line is mostly limited to the interior.
What exists as a range from question to concern outside the program, though, elicits different sentiments from USC offensive line coach Tim Drevno, who joined the Trojan Talk podcast to offer in-depth insight and perspective on the unit.

"I feel very good about it, to be honest with you. As a coach there's always years that guys graduate or leave early, so you've got to be able to fill those spots. I knew this was coming when I [moved from RBs to OL in 2018]," Drevno said. "The guys that we have, I feel really good about. Jalen McKenzie, we've moved him out from guard to the right tackle spot. We moved Alijah Vera-Tucker from the left guard spot to the left tackle spot. ...
"I feel good about Liam Jimmons, who made the transition a year ago from defense to offense, Andrew Vorhees is healthy and back, Liam Douglass has really come along, really developed and gotten really strong in the weight room. I feel good about Justin Dedich and Brett Neilon. I feel we've got a really good corps of guys, and the neat thing about it is they have really bought into Graham [Harrell] and the Air Raid -- this is an awesome offense. We're excited about it. I embrace this challenge, and I know that we have the guys in that locker room on the offensive line to get it done."
