Besides the mistakes in personnel that he made this year, I wonder if this might be more about if Dombrowski's vision for moving forward didn't align with the ownership and manager. Perhaps what Dombrowski wanted to do moving forward is completely different than what ownership wants to do.
There are different ways to approach this coming season: complete blow up, partial blow up, bring it all back with a few important additions, bring it all back with a few important subtractions, etc.
Did Dombrowski want to let Martinez walk and trade Mookie to try to retool the farm? Or did he want to do the opposite and keep them both by signing them to ridiculous money? And did ownership want the opposite? Was Dombrowski going to blame the season on Cora and fire him but ownership disagreed?
Guess we will know soon enough after the season ends.
