Not really in a lot of cases though
Mets - operated like this for an offseason, failed miserably, sold and haven't added anything of note this offseason
Padres - operated like this for a year or two, failed, and are now poor as f*** and slashing payroll
Dodgers - up until this season they've actually been pretty careful about how they spend, not committing long term to pitchers, and even letting Seager walk
Braves and Cards clearly operate under payroll constraints
If there's a lesson to be learned from the best teams, it isn't to throw whatever it takes at Cody Bellinger because he's the best guy available. It's to be willing to spend, but only on the right player. If their analysis tells them that he's the guy then they should make the investment, but if they see the same red flags we do, there's nothing wrong with going short term and making sure that their 200M or whatever is going to the right player.
