Cal was the most schizophrenic team in the country last season, and on defense at least, it wasn't close. Let's measure the multiple personalities using a nice, easy standard deviation number. Below are the teams with the highest standard deviation (i.e. the biggest range among week-to-week performances) using the Adj. Score measure you've come to know and love.
(You've come to know and love it, right?)
