Obviously Dak's in a better situation but I think you do him a huge disservice if you try to discredit his accomplishments just because of his supporting cast.
The Cowboys had a top 10 running game last year, the same OL, the same WRs (including a hobbled/injured Dez), and the same coaching staff. Obviously Zeke is an upgrade over McFadden, but overall Dak's in a situation that really isn't that different from last year's team.
Dak steps into a very comparable situation as Weeden, Cassel, and Moore and is excelling where they failed miserably.
So apparently driving this Cowboys' bus isn't as easy as some want to make it out to be. Maybe he's just so good that he's making it look easy and effortless. I prefer to look at it like that. That's why I refuse to assume that Wentz would perform just as well with this offense or that the supporting cast should get the bulk of the credit for Dak's success. Because we all saw last year that a strong OL & running game doesn't magically turn average QBs into good QBs.
So I'll give Dak his props rather than knock him down a peg.
