Just that he had the best arm and best feet and that his first two weeks were better than any two weeks Wentz had.
A couple things bug me about Wentz, though. First his yards per pass attempt was 11th, which is good but not great, and I think that is the single most important stat when judging qb's.
Second, Nick Foles put up better numbers in the playoffs than Wentz did in the regular season. I'm not even sure that the Eagles win the super bowl without Foles at QB. So there appears to be a lot in the Eagles system helping Wentz out.
Five years from now I think it will be Mahomes>Goff>Wentz
