I've posted along these lines before but our issue has always been not having enough draft capital in the first place. The scouting has seemed pretty good given what we've had to work with, and posters underestimate how many busts every team has and how uncertain the draft is.
The lack of draft capital isn't entirely their fault. It's hard to find spots for rookies on a really stacked roster (2013), the draft order heavily penalizes successful teams, and when you think you're currently in a Super Bowl window it's not attractive to stockpile with youth.
That being said, the FO bears the ultimate responsibility because they know the rules and how the system is set up. Trading picks away for players so often and not maximizing compensatory picks every year were short term moves that tried to stave off rebuilding as long as possible. However, you just can't sustain a good roster under the NFL's salary cap without a constant infusion of rookie contracts.
How bad were the other team's draft? Dang!
That's basically it. 2020 for example is looking pretty rough two years later; seven of the top ten picks have been underwhelming (or worse) and there haven't been many mid round standouts yet.
