Yes, Dombrowski finished the plan. Cherington would have finished it as well, had he been given the opportunity to do so. I can almost guarantee you that Cherington would have traded some of his prospects in 2016, and that the Sox would have been in the playoffs with whatever moves Cherington made. The team was already set.
I'm not arguing any results. I have said time and time again, that Dombrowski has set the team up well for the short term.
