Going strictly on this year to this point.-I think you can make a case that this is the best eagles offense ever. Lets compare it to 2004.
QB--Vick over Mcnabb. Hes just better in every facet of the game. Touch, scrambling, making the hard AND easy throws and tough as nails. Edge 2010 eagles
RB--B West was a beast in 2004 but Shady is coming along at an insanely high rate. Its hard to imagine but he may wind up being as good or even better than Westbrook if he can stay healthy. Edge-2004
Wideouts-TO,Pinkston,Mitchell vs Desean, Maclin, Avant --TO is the best single receiver the Eagles franchise has ever had but the 2010 tandem is miles better than the 2004 team.
TE--Celek has been better as of late but Chad Lewis is still the man here. Edge 2004 team.
FB--Josh Parry vs Owen Schmidt. --no brainer. Schmidt is a beast and can also catch the ball pretty well. Edge 2010
O line-- Clear edge to 2004 as they had maybe the best 2 tackles ever-at least as far as pass blocking. Not too shabby inside either.
I think because Vick is so much better than even Mcnabb in his prime--the 2010 offense is going to go down as one of, if not the best Eagles offense ever.
