I'm not spinning anything. You also didn't answer any questions.
Did he or did he not create a timebomb? I asked you what his hypothetical next moves would be had he stayed. The expectation of that roster was that they were on the precipice of winning the World Series. But this was actually fools gold because all of their best players were seconds away from implosion.
Here's a fun angle for you to see; the "core" of Bautista, Donaldson, Encarnacion, Martin, Tulowitzki, and Pillar which led the 2015 playoff emergence:
2015: 29.0 combined fWAR (AA's last season)
2016: 19.9 combined fWAR (team made the playoffs)
2017: 10.0 combined fWAR
That's a 66% decline in output just two seasons after AA's golden year (2015).
So again, what do you think AA's options were had he stayed. You spun my question into some other random point about Shanahan. Here's the deal: after 2015 the onus would be to keep pushing due to Rogers/fan expectations. It's NOT an option from an optics perspective to say "we need to shed salary and move some of these declining stars". You see that by 2016 your core position players have already lost 10 fWAR. ALL of them declined. By 2017, they dropped another 10 fWAR. That type of regression from the players who actually made your team a threat is impossible to navigate around without a stable of cheap young stars to step in; but we had no such players in our system.
What you fail to remember is that AA was seen as a failure all the way up until that 2015 trade deadline. He had made a bunch of trades and added on a shit-ton of salary and aging talent (Martin, Reyes, Buehrle, Tulo, Dickey etc.) and had nothing to show for it. Fans like yourself were actually calling for his firing. Isn't it funny how he went from "time to fire this guy" to "he's the best GM in the league" within the span of half a season?
You need to consider the decision from AA's perspective. At the 2015 trade deadline he was well on his way to getting fired. After the 2015 season he was executive of the year. But that 2015 team he built had literally one more season of contention in it. AA isn't an idiot; he saw what he created and understood that he was a season away from needing to go back to rebuilding under a new President, which means that he'd be the first guy out the door as his protection (Beeston) was gone. But he had just spent how many years rebuilding prior to 2015? The point is that all of the goodwill he had built would be gone in a flash and he would be left the scapegoat. He left himself no way around the inevitable collapse as again there was no talent ready to step in and he had no financial flexibility to attack free agency. I legitimately think had he stayed that you would have seen young Vlad traded for someone like Andrew McCutchen, which of course would have just delayed the inevitable.
Or, he could make the big-brained decision and simply cash in his stock while it was at it's highest point and not have to worry about any sort of rebuild scenario. He leaves and his reputation and stature is locked to whatever happened in 2015 when he left (ie: the savior!). He gets to name his next job (goes to the Dodgers under Friedman and learns more, something he was lacking under Ricciardi) and now he's the hottest prospect in the game. Again, the other option for him is to accept Shapiro's 5 year extension (which WAS on the table) and try to do a second rebuild in the AL East.
Could he have successfully rebuilt a second time? Quite possibly, but you left out some very key points. Most notably that his first rebuild was fueled by exploiting the broken qualification system that allowed him to stockpile compensation draft picks for free. That's where virtually all of his prospect trade-chips came from. Take a look at his last ~2 drafts after the MLB closed that loophole: there is virtually nothing there. So you fail to consider that he traded a lot of prospects, but also completely lost his way for quickly re-stocking.
Most of what you see of his success today is heavily dependent on learning from Friedman. He was a very flawed albeit talented exec with the Jays who was able to capitalize in 2015, but the refinement learned with the Dodgers allowed him to become a much more prudent decision maker.
The "reports" about Shapiro scolding him all came from the same legacy baseball media in this country who at the same time were writing love-letters to Paul Beeston, so how truthful do you actually think that was? Beeston was a renowned dinosaur of yester-year: a President who spent most of his time schmoozing and amassing goodwill. He had next to no baseball decision making. Those last few months of his tenure with the Jays saw all of his friends in the media openly campaigning for his job to be retained, so don't you find it a little convenient that once AA himself chose to walk away (again: he was in fact offered a 5-year extension) those same writers had the "intel" on Shapiro yelling at him? Really? What about Mark Shapiro comes off as a guy who has a temper? In case you forgot, those same writers were also championing the idea that Shapiro wanted to make baseball decisions himself (hence "pushing" AA out), however, that has proven to be completely false by actual reality. He has spent the entirety of his time here on stadium renovations and other non-baseball big picture items. So then why would you continue to believe that Shapiro scolded AA and wanted to push him out so that he could play defacto-GM, when in fact he had already stepped away from day-to-day operations years prior in Cleveland, and has clearly left day-to-day decisions in Toronto to the actual "front office".
