The descriptive explanation for why Cal lost so badly to Colorado is pretty simple. The one consistently above-average skill of the 2017 Bears has been a pass defense that has ranged from competent to downright smothering. Every other aspect of the team has been shaky. So if the pass defense were to disappear for a game against just about any opponent, Cal is liable to get blown out.
There, recap done.
Except why? What exactly happened this week that would lead to a previously mediocre passing offense to eviscerate one of the better secondaries in the conference?
