If you believe Wentz would have had the same kind of success on this team without Zeke last year and him tearing his ACL then you're out of your mind.
Wentz was elevated last year by having the right personnel around him, being in the right scheme, and being surrounded by good coaching. Nick Foles was able to win a few playoff games and the superbowl.
Football isnt as easy as plugging in a guy who had success on one team and expecting him to produce the same results (except for maybe Aaron Rodgers).
There is no way of knowing what kind of QB Wentz would be in Dallas. He very well could be performing just like Dak.
It would change a lot of things and Wentz could very well look like Dak if he were playing in Dallas.
Wentz is good, but no where near what you are making him out to be. He's no Aaron Rodgers.
