Do you think DD would have been allowed to trade Mayer, Rafaela, Duran, Bello, Casas or others had he stayed around?
Remember, he traded no major prospects after the 2018 deadline, and that was likely going to continue. In dreamland, we can envision he extended Betts and not Sale, had more to spend, and chose wisely on what overrated prospects to trade (like he did before.)
He could have traded Chavis, Mata and Groome, when their stock was highest. Later, he might have traded Dalbec, DHern and Jimenez.
I seriously doubt DD would have wanted to be here under the circumstances Bloom faced.
Change the circumstances for DD, then we should for Bloom, too.
IMO, keeping DD around would have only worked, if the parameters changed, too.
