While McFadden has looked good in the past, the Cowboys o-line has gone under some changes and isn't quite the same as it was the past two season!
I think there will be a bit of a downgrade in the production level we have seen from McFadden in the past behind this line.
I also don't think it is a sure thing he is the defacto #1, as Morris and him will have near a 50/50 split of the workload.
