Don't get me wrong, do I wish the Jones boys would shut up like Kraft? Sure I do.
But I also say we don't know the extent to which Jerry holds people back. For one thing, more and more owners want to be involved. That doesn't mean they make calls, but they want to sit in on meetings, too. It's not just Jerry doing this anymore.
For another, with the explosion in assistant coaching salaries, it doesn't happen that often that coaches get to hire everyone they want. This isn't the 80s or 90s where the head coach was in charge of everything. That only happens in rare cases like a Belichick or Gruden who have skins on the wall.
Bottom line, I don't buy the thinking that poor Jason would be a great coach except for Jerry handcuffing him. Jerry isn't ideal, to be sure. But I also don't buy that he's to blame for bad coaching. At the very least, it's not Jerry's fault that the HC can't manage a clock, can't communicate with his special teams during a game, and can't make the right call on when to go for it on 4th down.
Maybe Jason isn't a good coach and it's just that simple.
