2nd half adjustments are important, however they need to stop being soooooooo bad in the first half. 2nd half adjustments mean jack when you've lost the game by halftime. That is what will happen against PAC 12 teams once the season starts, if the first half defense doesn't improve.
The optimists among us are chalking that up to experimentation...experimenting with personnel and scheme, who can execute and how it matches up with opponents. I like to think they're approaching this like an actual preseason and that we're going to see a different team against the league.
I'm kind of a polly-fag like that. I'm not saying I'm a pollyanna or a fag. Don't twist.
