I'm not knocking DD at all, he was a great GM. I'm just not crediting him with building up the system. He built up the big league club and went for it and ultimately got a ring out of it so I'd be a fool to complain. In hindsight, he traded the right guys, but I think that's a lot of luck too. Nobody can predict with 100% accuracy a human being's future. For example, when the traded Moncada, I seriously doubt they thought he would bust but rather knew they had to part with a premium talent to get a guy like Chris Sale. DD went for the present and did very little to build for the future and I give him very little credit for the system.
That's not a knock on him as a GM, he came in and did what he was tasked to do, and to be fair if you go back to his earlier days he has a history of building up a system. It's within him to do and he's a smart guy....he just didn't do that here.
