Head over to Matt Melton's blog, Statistically Speaking, and check out his discussion on his SDPI statistic, specifically the SEC Rewind. Matt's found a pretty nice tool in terms of performance evaluation, as well as a tool that you can use in your repertoire for preseason predictive measures.
Matt has also helped me on my project, Adjusted Performance Percentage, or APP, and it's many branches. You'll be able to find things like ROAPP, or Rush Offense Adjusted Performance Percentage. Anyway, I have the SEC done, so expect that pretty soon.
APP, ROAPP, POAPP, etc are easy to calculate. You find the average yards allowed rushing (if you decide you want to know the ROAPP) by the 8 teams YOUR team faced in the SEC (adjust it for conferences who play more or less than 8 games). Then, take your school's rushing offense and divide it by the average allowed by the 8 opponents.
For Tennessee, as an example, their 8 SEC opponents allowed an average of 987 yards rushing in the SEC, while Tennessee rushed for 645 yards. 645/987 = 65.3%, or the worst ROAPP in the SEC.
After finishing the SEC portion of the project, I found that these ratings differ very little than if you just ranked every SEC team by the number of yards gained or allowed. It DOES change, however, and in the end, I will be adding the Total Offense APP (TOAPP) and Total Defense APP (TDAPP) to create Complete APP (CAPP). As a preview, Tennessee rates lower than Alabama in CAPP for 2006.

I came up with something similar to the APP (I call it the Modulus) that I use in my computer ranking system. For something like rushing yards, instead of dividing total yds gained by the total of all opponent's avg yds given up, I do it on a game by game basis. For Tennessee, their Rushing Modulus against SEC opponents is 0.595 which is pretty close to your ROAPP. If you're interested, I have all the statistics I keep in an Excel spreadsheet, if you send me an email (swcharles at gmail dot com) I'll go ahead and send it to you. It's nice to see other people who are trying to improve on College Football statistics.
