Invest in the Football Outsiders' Annual when it comes out in July. It's the absolute best tool out there for actual statistical analysis. They admit it's impossible to break out OL play from the film that they have (something that PFF doesn't do), and they only work from game charting data. But they're a great read and while I don't always agree with their analysis, they tend to be right quite a bit.
I thought they were STUPID last year picking San Francisco to win the division, but here we are a year later.
Oh I will this year.
The big issue is that outside of FO and PFF, the rest of the analysis out there isn't too in-depth.)
