UCLA didn't put a hurt on Cal.
UCLA did Cal a big favor.
It's a lost season.
And so this loss hasn't really damaged anything that wasn't already lost.
Now Cal has to take advantage of the reality that the press doesn't decide the outcome and they are going to have to go out and earn it each and every week.

Everyone picked Cal to be a top team this year.
Now they have to earn that.
And that is always more rewarding in the end.
