First of all, I do agree that it's time to raise the bar — it's ok to start expecting playoff success now. I think we can all agree that we've been playing enough postseason baseball to start feeling disappointed with these early exits. It's not 2008 anymore. It's ok to talk about a World Series.
I'll add to that by saying, I know it's not comfortable or popular to just blame it on "bad luck", and I'm not attributing it entirely to that ....but it's a big part of it.
If we walk Bellinger and Grandal in extras in 2018...maybe we win the game and the NLCS. If Grisham doesn't flub the ball in '19, maybe we go on to win it all. If Devin doesn't blow Game 3 last year ....maybe everything turns out differently. We'll never know. Then you have a similar small market, with less consistent postseason appearances like the Royals, get to the playoffs just two years in 2014 and '15, and they make the World Series in the first one and then win it the following year. Sucks to say "it's baseball", but I don't know how else to explain that. I don't think the Royals made all these crazy moves in 2014 and 2015 that resulted in this. But it's what happened.
None of this is saying we can't, and shouldn't, go get a bat or other weapon to improve our chances. That's fair. But it won't guarantee anything in this game. We can't have a better team on paper than the Dodgers. Doesn't mean we can't beat them, but we can't outspend and outinvest them. Unfortunately, the design of the game isn't fair.
One thing to keep in mind though — the real difference makers, the Ronald Acunas, the Gunnar Hendersons — they're not really available. Not for what any team would realistically spend, not without risking actually making the rest of the roster worse.
There's still assets out there that could help. But everything has to be considered. How does this guy fit into our system? How does he fit into the clubhouse? Will he be a seamless fit, or are we getting a Jesse Winker? If it's a position player, will he be a good defensive fit who will coordinate and communicate well with the others? (especially important when acquiring an infielder). Is the guy we are trading away crucial to the morale and general atmosphere of the club? I don't mean to suggest numbers aren't important — they are — I want a big bat too, but there are weird, unseen intangibles in baseball that just aren't always clear by the strength of your lineup. If there weren't, we certainly wouldn't have the best record in baseball.
