Honestly guys, I think Ralph is too old to really care about the football operations. Instead of being an owner to whom the top employees are accountable, I think he pushes that role to the front office, thereby creating an atmosphere where people keep their jobs a bit too long if underperforming. The Bills pay the price, but can you really blame him? There is more to life than involving yourself in the day-to-day operations of a football team, especially when you're as old as he is. Instead of calling his performance into question, we should wonder why he is adamant about keeping the team until his death. He should have already sold it to an owner who is involved enough to foster accountability within the organization, and I think Ralph may be past that stage.
Just to be clear, I could be 100% wrong about Ralph's current involvement, and my post is pure speculation. It's just the impression that I get.
