Maybe we will hear confirmation in the following months as to whether the Blue Jays training staff mishandled/misdiagnosed Josh's calf injury. This could be a major reason for his disenchantment with the Jays organization.
AA could have handled a few things better but overall he brought this team back-to-back playoff appearances for the first time in nearly a quarter century, including a 2015 that probably should have at least gone to the World Series were in not for some fortunate circumstances for the Royals.
All those moves were necessary for the Jays to become the legit playoff team they were for two years. The only prospect of any substance that has emerged from his deals has been oft-injured Noah Syndergaard. Pretty well all the others have developed into nothing of significant impact. If he had stayed pat, kept Syndergaard along with all the others, it is likely the jays would have been around .500 or lower from 2015/16 and the organization would have have the longest playoff drought in professional sports.
As for Martin, he has accumulated 7.7 war in just under 4 seasons on his 5 year/80 million contract. Not great value, but certainly not terrible let alone one of the worst contracts in pro baseball. In 89 games this season, he has 10 homeruns, and while his batting average is terrible, he has a respectable .338 OBP. He defense is still decent/above average as well. I suspect he will be splitting duties with Jansen next year along with a dose of Dhing and Pitch hitting.
