I'm not convinced of that.
So far we are replaying the cycle of the 2008 WS team era. Team that shouldn't get to WS does. Even wins it in 2008. Then the team adds a lot of expensive talent, trades kids and loses draft picks while expanding budget. Although succeeding teams win more games, each year they do worse in post-season than they did the season before. In 2008 sequence, the next step was a crash in 2012 starting roughly a decade of prolonged dismal, due to weak minor leagu.es and drafts and not aggressive budgets. Basically a rebuild not managed at all well.
Is that the next step for this team. The current team has a big budget, an aging core - some with long/high $ contracts, and a relatively deep farm which just traded two key prospects (yes, the trade made sense, but unless you use the new guys to progress farther in the playoffs, you lose the trade. We still have Duran for next year so ledger is still open, but this year was the key goal, next year is a tougher situation).. This is like the Pence trade. He helped at the end of a regular season, where we had the top seed all but sewn up before acquiring him, then did nothing in the post-season, then started off the next season poorly and was traded for little.
What happens next year is the really big question. Do we enter a new dark age as we did in 2012? Do the Middleton bucks allow a rebuild on the fly?
