Eric summarized it nicely, but when one of your team's strengths is defense that shelters you considerably from regression. Shouldn't we, as Twins fans, know that as well as any? The Royals also field a defense far better than any we did in the 2000s, that's going to insulate them from sliding too far off what they did last year. The real question for the Royals is how do the complement their defense? Barring major injuries they are pretty much a .500 team just with how well they play D and shut teams down with their bullpen. I think the real keys are their young offensive players. Hosmer was a much better hitter the second half of last year. Moustakas had some flashes of what he is capable of and they still have some solid players in Perez, Gordon, and others. If that offense can pull itself out of being in the "dreadful" category, they may actually get better. Cleveland, in my eyes, is the team to watch out for.
