Over the last 40 years, I count only 3 seriously regrettable trades concerning the prospects lost: 1. Melvin Mora for Mike Bordick, 2000. Admittedly with some benefit of hindsight. 2. Scott Kazmir for Victor Zambrano, 2004. No hindsight required, it was dumb at the time. 3. Pete Crow-Armstrong for Javy Baez, 2021. (I’d guess I’d also consider the July 2002 deal for Reed/Middlebrooks that gave up Jason Bay). Whether the deals worked (Leiter, Piazza, Delgado, Cespedes, Lindor), didn’t work (Alomar, Cano), or worked but didn’t make a difference re: playoffs (Viola, Santana), the Mets weren’t burned on the prospects lost.
