Who has the better running duo in NFC east?

[NYCSkin]

I like the big back/scat back duo that the Gmen have. However, the offensive lines of these teams play a huge role in determining the best duo. Right now--I think Dallas' O line is the best run blocking line and therefore Barber and Jones have the best numbers. A great running back cannot compensate for a poor Oline. A great Oline only needs an above average back to produce good stats...
