At this point, the only way you can conclude that Wentz is a better pro QB than Dak is if you really really really use your imagination.
You have to imagine how much better Wentz would be performing if he had a better supporting cast on offense.
You have to imagine how poorly Dak would be performing if he wasn't surrounded by such a good offense.
You have to imagine that the Philly WR's and TE's are 100% completely incapable of gaining separation from defenders, as this justifies Wentz's dinking and dunking.
You have to imagine that the Cowboys' 2015 season never happened, that way we can say any QB could perform well in this offense, thus negating Dak's stellar performance.
You have to imagine that Philly's coaching staff is for whatever illogical reason not allowing Wentz to unleash that cannon of an arm on opposing defenses, because we all know he has such as amazing arm. Even though we haven't seen it yet.
So you see, all of us who haven't adopted the Wentz fetish yet, just need to work on using our imagination. Our problem is that we're stuck in reality, where, Dak has performed better in every possible way.
