Nobody would trade the end result of 2017 for anything, but as is the case with many teams, success sometimes makes key figures develop an ego that's too big for their own good. Remember, entering that Super Bowl, we were touted as a team that was built to stay atop our division for the next half decade, and now we find ourselves stuck in quicksand three seasons removed.
With Doug now gone, if we look back, he showed a ton of signs that his ego started inflating. It started with the book he wrote (can't blame him for capitalizing on his chance, but still), then it felt like he stopped adjusting mid-game and turned back into Andy Reid pre-Mahomes. The team was poorly prepared to play in too many games to count and threw away a ton that they were supposed to win. Then, after a terrible season in which we didn't have an OC, he decides he'd promote from within rather than bring in an outside voice.
As for Howie, it feels as though winning it all convinced him that he's been "right" all along (especially after the lone year of Chip Kelly being in charge of personnel). Never mind that his drafts have produced so few Pro Bowlers or how often he'd taken disappointments over studs even before Chip Kelly's interruption; Howie stuck to his guns. The Patriots flat out exposed our defense in that Super Bowl, but because we won, it seems as though he didn't feel a need to fix it, and QBs continue to tear us up.
I maintain that Jeffrey is still a good owner, but winning it all may have also convinced him that his loyalty to Howie is warranted, even in the face of evidence that suggests otherwise.
I didn't expect a duplication of 2017, because the stars can't align for us like that every year, but to fall off like we've done...how much of it is because of ego?
