LOS ANGELES (AP) — No. 6 Southern California opened the season with a 56-28 victory over San Jose State. Caleb Williams passed for 278 yards and four touchdowns in his return from his Heisman Trophy season, and freshman Zachariah Branch made an electrifying debut with a 96-yard kickoff return and a 25-yard reception for touchdowns. Dorian Singer, Tahj Washington and Brenden Rice also caught TD passes and Austin Jones rushed for two more scores as USC opened its second season under Lincoln Riley with another impressive offensive performance that easily covered the Trojans’ persistent defensive flaws.
