Yeah I don't think anyone is arguing those two trades weren't his best, but to define his tenure here by just those two deals is ridiculous. I think most of the decisions and moves by AA here were solid. He's the one who made baseball relevant again in the city of Toronto and across Canada.
As for the Marlins trade:
- Hech had a -1.3 WAR in 2013. He was solid in 2015 posting a 2.6 WAR. Otherwise, not really missed.
- Yunel Escobar like you said was traded for political reasons, so AA had no choice. Marlins moved him to Tampa after and he had a 3 WAR season. Maybe Yunel doesn't get traded if he wasn't acting like a jerk.
- Handsome Jake didn't do anything with the Marlins. He had solid years with the Astros as a 4th outfielder: 1.8 WAR, 1.2 WAR, 2.1 WAR seasons from 2015-2017.
- Henderson Alvarez had a 2 WAR and 2.5 WAR season in 2013 and 2014. Wouldn't have made a difference in 2015 and 2016 whatsoever.
- Anthony DeSclafani had solid years once he was traded to Cincy - 3.1 and 2.1 WAR seasons in 2015 and 2016. Has had a solid career as a mid-rotation/No.4 type starter.
I'm not losing sleep over any of those guys to be honest. All of them were easily replaceable. We're talking about a slap-hitting/utility player, a 4th outfielder, and a starter with low K rates. Yunel was solid in 2013, 2015 and decent in 2016. Anthony DeSclafani was the one who ended up having a solid career, and would have been useful in 2015 and 2016 but oh well.
