good website on Soutbern Cal offense and defense

Another interesting thing I noted from the article reviewing a Norm Chow video from his days at BYU:

3) There are a relatively few plays his teams run a lot (e.g. a Pareto rule) that make up 80% of the pass plays or run plays. Then there are a lot of special plays or adjustments that make up the remaining 20%.

Ties in with some other discussions going on. In general that website is worth having a look at.
