When you are the owner of a sports team, the reason you hire someone else to be the GM is to ensure you have someone who doesn’t/can’t fall in love their own players because their job depends on it.
The problem with JJ and SJ is they fall in love with their own players, believe in best case scenarios (because their jobs and livelihood do not depend on it) and they do not possess the football talent to do it right.
Jerry Jones is an absolutely great businessman. One of the best. But his skill of optimism kills him as a GM. Because he believes in his football choices and decisions too much. It works great in business situations, not in roster building.
Because it is a killer for the cold hard decision making skills required of a GM who must win playoff games. Jerry is a GM like a fan would be. He gets sentimental about players and coaches. He keeps players too long. He’s slow to recognize problems until they are obvious to everyone. He’s like a dad who genuinely believes his high school athlete kid is a star, and they’re not. Jerry is incapable of being a clear eyed cold and successful GM. He’s like a fantasy football player.
Jerry cries every training camp talking about how much he loves his team, his coaches and his players. Sadly I believe him. And it’s exactly why the winning owners of the last 28 super bowls all recognize they need to hire someone else to build the roster.
Jerry is good at business but terrible at football, and he doesn't understand his own limitations or what gave him initial success at football. Worse yet, he has now put his placeholder, who is even worse at football in charge.
If he made his money on winning football championships, he'd be broke.
At one time he let someone who knew football take care of things, likely because he was a newb to the NFL and didn't have much choice.
But his ego quickly convinced him that he was the one responsible for the success, despite never having recreated it in nearly 30 years. But his pride won't let him change. He will die trying to convince the world he knows football. He wants this more than anything.
He loves marque players. He loves the hype. He quickly anoints players with modest initial success as Hall of Famers. He capitalizes on their marketing potential.
But he's has no idea how to create a team that functions together at a high level, when needed most..
He's the NY rangers of football. who get bounced out of the playoffs despite President's trophies.
