Personnel Turnover - Football - An Analysis of the Pac 12

As a preface, this is an incomplete analysis (hoping all of you will make additions and corrections) as there are few if any sources that track college football roster turnover.   Moreover, only front line players seem to generate searchable news so it’s almost a certainty that we’re missing departures outside of Cal.   However, we feel this gives a relative sense of how to view the Bears roster turnover vis a vis our closest competitors.
