He's well paid to do this very thing.
Let me put it to you this way: I am a computer programmer, and it blows my mind how little people understand my craft and what you can or cannot do technologically. Clients all the time imagine that an entire refactoring of their codebase is a "few weeks" worth of work since, in their mind, it's just a bunch of copying and pasting. In reality, a tiny change in one part of the codebase could have unforeseen ramifications throughout the entire program.
When NASA designs their software for the space program, they have to certify that their code is 99.9999% bug-free, when the average rate of programmer error is one bug per 300 lines of code, and the average commercial program contains over 500,000 lines of code. That's over 1600 errors, yet the average person whose total extent of technical know-how involves pressing the on-switch assumes that their computer is supposed to be error-proof and read their mind and bitch non-stop otherwise.
In the same vein, a top of the line general manager has a bust rate of around 50%, meaning that a pick they make is likely to be out of the league entirely within three years over half the time.
Absolutely elite GMs only raise this percentage by a few points at most, meaning the fanbase can make wild assumptions based on 20/20 hindsight on how their GM is totally retarded when they understand nothing of the process and the inherent randomness involved in it.
This isn't Madden.
I'm sure you are fantastic at your job, but competence isn't necessarily a prerequisite to employment-something you may have even observed within your field. JR likes to keep his kind of people close to him. I also think you are assuming that having a position within a particular field implies a certain level of acumen in that field. This may or may not be the case depending on many circumstances. If everyone was well-suited for the work they are doing, there would be no firings at all. Hurney, in my opinion and for numerous reasons outside of the draft, is incompetent in his role. Morevover, we'll never reach consistent greatness as a franchise until we have a new owner, but that's a whole different conversation.
