What about the times we stopped Cal outside of the RZ?The Cal offense went into the RZ 6 times and 6 times they came away with a TD. If you want to make an argument that this is an average defense, you better explain why there weren't any FG attempts or turnovers inside the RZ.
Also, per your stats, our D only let Cal move into the RZ a total of four times... that's actually very good, especially considering Cal has like the 17th-best offense in the nation.
Our D also had three fourth-down stops and got a turnover. And we held in the third quarter until our offense was able to finally put up second-half points and pull away.
If you add up all the "good" things our defense did along with the "bad," what you end up with is an overall average outcome. And I'll say the exact same thing about our offense. It wasn't our best showing in any phase of the game... even our special teams (a great PR, but also a muffed punt) were hot and cold.
But if you only focus on the bad stuff, then of course you'll think it was all bad.
