Most of these replies fit with what I was going to say, so I'll omit my Bullock for Diamond comment. Sure it looks bad now, but where was everyone when the trade was made? Oh! That's right! We all knew it was a stupid trade then. Which leads me to my point:
The Twins have done way too many stupid things through the years to deserve to win anything. What really happened was they got lucky. They got lucky that a certain group of players (Koskie, AJP, Minky, Hunter) had the right stuff. That at the same time these guys were developing got lucky that tthree draft picks were MVP-caliber. Still they made great decisions on Mauer, Morneau, and then Santana in Rule V...but they got lucky. Most good teams get lucky like this, so it's not a denigration. They also had a great manager in Tom Kelly. When Kelly left, he had them ready to win. Add in the MVP-types, and you get a decade of success in a poor division.
But besides getting lucky, an organization has to do smart things all along the way. Gardenhire was a consistently poor manager, Ryan consistently a poor GM, and Smith maybe the worst ever. Ryan has some redeeming qualities...almost exclusively in the scouting and development areas, so if he never makes a major league move, it's an optimization of his abilities.
Let's face it. Everything lucky thing happened at the right time...when Cleveland went downhill, and Detroit was floundering, Chisox mediocre, KC just pure sucking. Now Detroit and KC will be strong for years, and the Twins don't have the players, the smarts, and certainly not the manager to really be able to compete on a consistent basis...there might be a lucky year in the next ten. I expect the football Gophers to compete better this decade than the Twins will.
