Cal has the sad distinction of being, statistically speaking, the worst defense in the country.
The Bears (5-18, 0-11 Pac-12) ranked last among 351 Division I teams in field-goal percentage defense, allowing opponents to convert 50.6 percent. Nine of 11 Pac-12 foes have topped 50 percent against the Bears.
Cal does not have great size, so they are a poor rebounding team, prone to allowing second-chance points and lots of scoring in the paint. But in their most recent defeat, Saturday at Oregon State, the Bears gave up just nine second-chance points.
So the answer is not as simple as just one thing.
We asked coach Wyking Jones why the Bears aren't better defensively more two-thirds the way through their season. Check out his response in the video above.
