JD is a convenient scapegoat for all of the cultists who wish it was still 2005, but the uncomfortable reality is that the brand and company started its downward spiral well before Jay-Doh took the reigns. For example, Nike completely dropped and ignored the running market, especially the exploding trail running market, ceding it to On, Hoka, Salomon, and Altra. Billions in revenue left on the table right there. By 2020 it was a shell of its former glory, focused mainly on pushing yet another boring colorway of the Dunk, and slapping the swoosh on ugly sweatshirts that invariably ended up on a clearance rack at an outlet.
JD correctly recognized that falling revenues and product quality coupled with a bloated, directionless structure focused on everything except the actual product was a recipe for eventual disaster. He was correct in noting that better manufacturers don't run their businesses and supply chains solely using MS Excel and Powerpoint, and pushed back on the corrosive "not made here" and "that's not how Nike does it" attitudes endemic to those inside the berm.
He may have been the hated executioner, but what exactly has EH done that differs in any substantive way from JD's plan? Putting on a smile and bringing a jocular "I like sneakers" attitude while laying off yet more people and demoralizing the survivors? Begging Big 5 for more shelf space? OK, maybe that, but isn't that a little late and a dollar short by now?
