What almost every ownership group wants is obvious. They want to be the Tampa Bay Rays or possibly the Cleveland Indians. They want to be a team that wins constantly with a low payroll. That's the goal. What's more important out of the two? Sadly the low payroll, so if they don't win that's not the worst thing that can happen.
This differs from what the fans want which is simply to win. They want to see playoffs and championships. If the team doesn't win that IS the worst thing in the world. And that's where the conflict happens, or at least where it should happen. Now spending money is FAR from a guarantee of success, but the numbers are pretty clear that spending money is better than not spending money in regards to making that happen.
An ownership group has three options then (1) ignore the fans as they aren't the most crucial money driver unless you create a big fandom, (2) give in to the fans and spend some more money, or (3) convince the fans they are wrong and spending money is actually bad. Despite the multiple Dodgers titles and the Yankees and Phillies always in the playoffs, they've done a very good with (3). "We can put that money back into player development!" "Sure we could have an ok team now, but don't you want a GREAT team later?"
That's where the Nats are now... well sort of. What we know is the Nats have a do fun team now that could still make the playoffs and could have had a better shot if the Nats FO did something earlier. It wouldn't have been likely to really contend but with nothing certain for the future is it better to lean in when opportunities are presented to you? That's the philosophy question I suppose. What is increased chances at a long set of playoff runs and real title contention worth to you?
In theory that could be worth a lot, but I think fans tend to skew those chances, (and they aren't helped because that's what the owners are always selling you). In their minds it's like "sure we could go to a 66% chance of a WC spot for the next couple of years, but we can have like a 90% chance of a long playoff run starting in three years if we don't!" But the reality is more like "sure we could go to a 66% chance of a WC spot for the next couple of years, but the Nats have a 20% to have another long run starting in the next couple of years, we can up it to maybe 35%!" That's what you are throwing away pushes right in front of you for.
This is an all-time argument in baseball though and not one easily answered, because those long run results ARE so good and these short unexpected runs usually are just a couple of meaningless fun series. But it IS risk / reward. The payoff is high, sure you could be the Rays or Indians but the risk is real, you could also be the Athletics or Pirates or Rockies or Royals...
My question though is - do fans really want to be the Rays? The key to the Rays is the constant churn. Have a guy, he gets good, send him off for some young guys to replace him, rinse, repeat. There is no core set of players you are rooting for, only truly a set of laundry that guys fill aged 20-27 before heading off elsewhere. If you do it right occasionally that group comes together to matter, but when they don't you have a team that is bad that also engenders no loyalty. The Rays are consistently one of the lowest teams in attendance good or bad. These things are connected.
But maybe the Nats are already one of these teams? Bryce Harper, Anthony Rendon, Juan Soto, Trea Turner. All stars. All gone. What made the Nationals different was never a commitment to young players to age with the team but the willingness to go out and grab 1-2 big time FAs to be the final pieces. If the Nats don't keep CJ Abrams, that's nothing new, but simply the Nats being the Nats. Where things would be different is if after that happens they don't spend any money. There is no follow-up Scherzer or Corbin.
Really the most important thing here is we don't know what this Nats organization is going to be like. This isn't the Pirates or Rockies with decades of proof they don't know what they are doing and don't care. This Nats org could trade Abrams and use that saving to then bring in Skubal. So all these arguments about should the Nats have done more this year are sort of made in this great vacuum of knowledge. If the Nats are a team committed to winning that just want to set-up the best team possible when spending money then no they shouldn't do anything now (or really it was ok they didn't do anything earlier - it's a bit too late now). If the Nats are a team just hoping to "out-organization" to be the next cheap-o Rays or Pirates whatever the results may be then they should have gone for it. But we don't know.
As far as getting that knowledge the trade deadline will tell us something. The off-season will tell us more.
