Weekly Depth Charts?

[gopatriots]

Hi there, as a strictly offline dynasty player and trying to keep my simming realistic as possible, I was wondering if anyone knew where I could find weekly depth-charts for last season? Preferably starting with the pre-season. I tried searching but can only seem to find the current depth charts for each team.
Thanks

I think your best chance of finding any weekly depth chart info would be the gamebooks on NFL.com.

Pick a team, upper righthand corner lets you pick the date of the depthchart.

I love that site.
