Preller's string of bad trades is legendary.

2014 - Yasmani Grandal and Zach Eflin for Matt Kemp
2015 - Jedd Gyorko for Jon Jay
2015 - Max Fried for 1 year of J Upton
2018 - Hosmer deal
2020 - Naylor, Quantrill, Gabriel Arias, Owen Miller, Joey Cantillo for Mike Clevinger+
2020 - Taylor Trammell, Ty France, Andrés Muñoz, and Luis Torrens for Austin Nola, Dan Altavilla, and Austin Adams.
2021 - Jack Suwinkski, Tucupita Marcano for 4 months of Adam Frazier
2022 - Soto deal.
2022 - Brent Rooker for.... Cam Gallagher? To be fair, KCR waived Rooker later on.
I am probably even missing a few stinkers.
Yeah he's made the odd good trade too, but come oooonnnnnnnnnnnnnnn. This guy a f***ing idiot. He has burned so much value on trades that I am shocked he still has a job. This doesn't even mention any signing other than Hosmer.
The Padres are competitive in spite of him, not thanks to him. His best contribution has been convincing ownership to raise payroll. You have to give him credit for that, at least.
But most morons with a $256,000,000 payroll in a salary cap sport could be a bit competitive. The Padres missed the playoffs with the 3rd highest payroll.
