I'm guessing, from the way you worded your first post, that you started this thread with an assumed correct answer in mind (Kansas City).
Before we start anointing them the most promising franchise in baseball, let's just remember that the Kansas City franchise has looked promising for years, but has never really delivered. They have had only one winning season since 1995, and haven't made the playoffs since 1985. The Twins, over that time, have had far more success, and while the next couple of years may be unsatisfying, their track record shows that they know how to build a team that contends.
I would also disagree with your statement that they have not started rebuilding and are in denial of the need to do so. Every interview I've heard this year with management shows they know the hole they are in. Their drafting strategy this year, heavy on power-arm pitchers, shows them trying to address identified needs. Just because their rebuilding plan differs from your vision of what it should be doesn't mean they don't have one and are in denial. Time will tell whether or not their plan works. Kansas City's so far hasn't.
