Looks to me like it was a sound idea to trade Polanco, given his declining defense / health and then he had a poor 2024 season. As Hambino said, the package they took back was a strange one, trying to mix some marginal bullpen and rotation help with a prospect who was by far the most valuable part of the deal.
Not sure why anyone would lump his 2025 season in there when he hit the open market and any other team could have signed him away, and if that happened we wouldn't count that against the trade. Nothing was stopping us from bringing him back.
I'm interested to see what Gonzalez can do in the majors... still odd that he was the most valuable part of the trade, a 20 year old outfielder who was years away from helping the team. In the context of the 2024 season it didn't help the team and I think Falvey did a poor job in the short term. Long term, well, they already have a bunch of OF prospects and added more at the 2025 deadline. At the time of the trade I wondered if they'd flip Gonzalez for a veteran to help the 2024 roster, and I stand by that. So on paper, getting Gonzalez and change for one year of Polanco out of his prime is a good move, but the move didn't synergize with what Falvey was doing with the rest of the roster.
