Some of that is just a new boss. Some of that is fine.
I do share your concern on some levels. The team's scouting was among the best - as was the development and analytics. You hate losing good people.
Dombrowski has been a very successful executive - albeit in an older school sort of way, which is not bad. This philosophy is good for this team in the shorter run - the longer term is an open question, but I don't expect Dombrowski to be around to worry about that, so what does he care? If the team wins a title or two in the interim, it works for him. The team he has left - as you'd expect - shapes up to be very good, but yes, with a little higher risk than existed under the previous administration.
Again, the fascinating thing is the Red Sox breaking up a best-in-industry sort of front office. It is weird to see John Henry seeming like he has been possessed by another human being.
