I think that makes them smarter than us. Their 2020 was the equivalent of our 2018, they weren't supposed to be ready to contend. And when the bottom fell out on us in 2019 they still had to be buyers to try and stay afloat (and we had nothing to trade anyway, everyone was injured). The Marlins know they aren't going to win the NL East, it's time to start retooling already.
Still wonder where the team would be right now if they'd just won 65 games in 2018 with no Arrieta or Santana, and if they'd then kept Crawford and Alfaro and not traded for Segura. Possibly that 2019 team would not have been better - though it's a low bar - and they would have still needed a starting pitcher, but they'd have had a whole lot of money to make different fixes over the past two years, and maybe Crawford/Kingery would have established themselves up the middle. Of course Sixto would be no more useful than Howard (less, technically, at the moment).
