"Dak & Wentz are not on same level"
I would say they are. Each has their flaws, Wentz's durability is a big minus on him, Dak's missing of critical throws is a big minus. Wentz's best year his completion percentage was only 60.2%, Dak's worst year was 62.9%. Wentz had 33 tds in 13 games, Dak had only 23 in 16 games.
But to that you have to factor in the rest of the team, Wentz's best year the Iggles had the no. 4 defense, Dak's best year the Dallas defense was only 14th.
Really though, with only 40 and 48 games played (plus Dak's 2 playoff games) each can and probably are still developing, and with those limited games it's still too early to really evaluate both of them. To me each has to improve, Wentz has to stay on the field and improve the completion percentage, and Dak has to make better decisions and tighten up on the badly missed throws he's prone to make.
Assuming each plays a full season and the defenses are not that far apart, by the end of this year it will be much easier to agree or disagree with the article title...
