But that's the point. KC didn't maximize the value of their ML talent (I am supposing here but think it a good supposition) and their "rebuild" took almost a decade to achieve. They were horrible year after year after year. Moore gets credit for turning things around, and he certainly was a big part of it, but the core of the KC team were high pick draftees taken from 2005-2008, give or take a little.
Now, they are a year or two away from losing Hosmer and Moustakas, Wade Davis, Lorenzo Cain, Hochevar, Escobar, Duffy, Morales, Volquez, Vargas.
They have two guys on MLB's top 100 list with one being an over-rated 2B/SS who is getting some mileage out of his legacy name (Mondesi) and has bust or limited value, written all over him and a pitcher with health problems. I would say that their farm is easily bottom third in the league and mat actually be bottom 5 at this point.
KC will keep some of the guys listed above but I don't think they will keep Hosmer or Moustakas or Davis (assuming health). And yes, they ARE spending more but they will never be a large market team. I think they know they have a window and are spending to win while they can, but will tear down and rebuild when the bottom falls out. Their highest paid player is a 32 YO who is currently hitting .207 and will be on their books through 2019 with a $4M cherry for 2020 (but hey, he plays defense). That bit of sentimentality is going to cost them. Arguably their best current pitcher, Kennedy, is 31 and signed to a big contract through 2020 at about $16.5M. Even assuming that both those guys remain at least useful, they still will account for about $37M per year out of the payroll through at least 2019 or about 30% of the payroll as it currently stands which is probably about as high as it can go so as the record declines and the payroll falls those two make up a higher percentage of the payroll paid likely for diminishing returns.
I think they are headed for a #3 or #4 place finish within their division this year with about the same next year and a significant decline after that.
But they did get the ring, which is what you play for.
Pittsburgh is a different story in that they have been close but never decided to "go for it." They have largely been working off the assumption that they can generate a WS winner with home grown guys. And that might work. But so far it hasn't. I think they have a chance to be relevant longer than KC because they have been more aggressive in trying to sign their young guys to long term deals. Their farm is also in much better shape. But, if they start having young guys who go through arbitration and want to be FA, then they are probably doomed because they won't spend to keep them all and unless they are really lucky (and good) they will have a harder time keeping the farm anywhere near as good as it has been.
