There’s no ready-made answer, and USC’s offensive-line consistency will be one of the storylines of the season. When tight end McRee went down in a heap Saturday after a low hit, his limp off the field was a gut-wrench, the broadcast showing the USC stalwart breaking into tears on the sideline.

Doman averaged 49.1 yards per punt, dropping four punts inside the 20. His distance and hang time limited USC's electric punt returner Zachariah Branch. Third down defense: USC went three-and-out on its first three drives and only picked up one first down its fourth possession.

There are highs and lows every week in college football. The winners and losers for Week 4 start with Southern California's loss to Michigan.
