I mostly agree except for the bold. I do think the front office a.k.a. Jerry Jones does care about team goals. However, my opinion is not generally shared by others.
In all seriousness (dead serious), I think Jones believes he is always making solid, final decisions in terms of coaching and player acquisitions, hiring, firing, contracts, etc. Why? Because he has always projected himself as a qualified, knowledgeable football operations executive. Now, I do not believe that is a true self-assessment in reality. He is lying to himself. However, I do think he believes it is absolutely true. As such, I believe he sees each shortcoming of the team every year as a by-product of what his coaches and players did not accomplish--and not because of the decisions he made leading up to the beginning of each season. In short, he shifts 'enough' blame from himself to others.
That type of mindset believes he has done more than enough as a general manager to achieve success a.k.a. team goals. The reality is that he has never solely formulated the correct mix of coaching and players in any given year to achieve those same goals, since he bought the team, over 35 years ago.
That is just my opinion though. Opposing opinions vary but generally state Jones is consciously and purposefully sabotaging team goals every year, usually based on the perception of self-greed. For example, Jones keeps <fill in the blank player> primarily for jersey sales. Yes he does. Every business person wants to be profitable. Jones is not the exception in that regard. Unfortunately, the logic is faulty. Jones can achieve higher profits via jersey sales with a better player.
Thing is, Jones thinks he has the 'better' player already and risks losing the 'better' player by acquiring one he has not already assessed for himself as being the better player. That is not greed. That is shortsightedness, which is a poor quality in a general manager of any professional sports team. That's Jerry Jones.
