Many of USC's defensive players are shifting to new positions in the Trojans' "52" scheme.
Morgan Breslin and Devon Kennard are morphing from ends to hybrid linebackers. Leonard Williams moves from tackle to end.
Meantime, third-year sophomore Antwaun Woods keeps working at his craft as a nose tackle.
"No difference in my world," he said Tuesday.
The 6-foot, 310-pound Woods started the first four games last season and then played as a reserve, finishing with 4 1/2 tackles for losses, including three sacks.
Coaches and teammates said Woods is among the Trojans' most knowledgeable players.
"He's a very smart kid," defensive line coach Ed Orgeron said.
Woods' has a simple goal this season.
"Just being accountable," he said. "Knowing that I'm in there, I'm going to get the job done."
