The No. 8 USC football team kicks off its 2015 campaign with 3 consecutive home games, beginning with a Labor Day weekend encounter under the lights versus first-time opponent Arkansas State. The Trojans have won their past 17 season openers. It’s the first of 2 straight encounters against Sun Belt foes, as Idaho visits next week (the last season that USC hosted back-to-back non-conference opponents from the same league was in 1953). USC head coach Steve Sarkisian has a deeper squad that he had in his 2014 debut season, with 77 scholarship players (including 16 returning starters).
