LOS ANGELES — Pregame warmups are always full-out before the USC football team takes the field for kickoff. Just like practice.”But somewhere between warmups and the first snap of Saturday’s 34-32 road loss to Illinois, that intensity was lost. We just gotta attack practice better, better mentality. We’re looking to be great.”Illinois totaled 502 yards of offense, and the 331 yards passing and 171 yards rushing were both season-highs allowed by USC’s defense. “They really just pushed us back,” Pierce said of Illinois.
