Rankings like this are interesting, but it's kind of like those "Top Ten Places to Live" rankings. The final evaluation depends on how you define and weight variables, and different surveys by different smart, thoughtful people will find different answers. It's easy to do, mathematically, it's defining the variables and weights that's hard (and arbitrary). Being a GM is a big job, with a lot of things you can control and a lot of things you can't. Dayton Moore's team looks good this year, but this is his 9th year as GM- how should you control for that? Is there an average amount of time to turn things around, so you should beat that? Etc.
