From the perspective of another Eagles fan, that's actually a pretty terrible take. Douglass prompted Howie to make some good FA signings (and I think Foles was more Doug Pederson and Howie than Douglass), but the three drafts that he had input into, 2017, 2018 and 2019, don't look very good. (He was hired in 2016 after that year's draft, in which the Eagles traded up for Wentz.) Those three drafts have yielded a grand total of two impact players, Dallas Goedert and Miles Sanders. To be fair, there wasn't a whole lot to get in the 2018 draft due to picks lost from the Wentz trade, but only 2 of 8 players remain from the 2017 draft, and every pick from 2019 aside from Sanders looks dreadful.
Sorry to rain on your parade.
