I didn't watch all the games, but regarding the west, USC looked sharp right from the onset. I know this is the first actual game of the year so I will make concessions for both good and bad performances. UCLA and Cal were disappointing. Boise came out strong, but faded and UNLV looked atrocious. UNLV will not win 4 games this year.
Should learn a lot more next week when everyone's had time to make adjustments.
Also, Alabama looked like the more athletic team in just about every position, but the offense just doesn't looked equally skilled. Yeah, they run the plays, but there's no game breaker. But again, Saban's no dummy and I'm sure they will make the necessary adjustments.
The old adage will hold true: Good teams get better, average teams will get worse as the season goes on.
