First, during all of the criticism, I don't think anyone attacks Dick personally. It's a widely held belief that as a person Dick seems to be a nice guy.
Second, I think you are ignoring the fact that early on Dick had a huge say in shaping HIS football team. Dick wanted the Tampa-2. Dick wanted fast and lightweight D-linemen. Dick wanted to acquire Db's through the draft and Dick got what he wanted. Dick chooses to run soft training camps. For four years he has been unsuccessful and it wasn't because of some kind of structure that was forced upon him.
