If Cherington worked magic a year ago, he did not become an imbecile overnight. I was on this board last offseason - most applauded his relatively restrained offseason - although intelligent minds differed on the Ellsbury business. (as it turned out, they were not necessarily wrong in not signing Ellsbury, but Bradley did not hold up his end of the deal) The AJ signing made sense as a contractual stopgap - they did not want to commit to anybody with the kids coming. The Drew re-signing made sense also (basically the bet was Bogaerts was better than any free agent 3B) though intelligent minds could disagree there surely. Mujica was a nothingburger (useful guy for what he is).
Indeed the team DIDN'T insist that Bradley be in there hell or high water - that's why they gave Grady Sizemore's entrails a starting job over a good three weeks in Fort Myers. If anything, they should have done that - but they did not have a winning strategy for him. They got weak kneed with Bogaerts too. When you see how hopeless Pedroia was in his cup of coffee in 2006, there was proof that you are better off standing behind your evaluations than, say, listening to what talk show callers say or what a decrepit former MVP-sort did over a random month against future minor leaguers.
