The last three lines of the portion of the article said; "In fact, when Dombrowski arrived in Boston, Kennedy picked him up at the airport. Dombrowski asked Kennedy to arrange a meeting between him and Cherington. He’d been hired and didn’t know Cherington was already gone. A year later, Hazen, Jared Porter and Amiel Sawdaye, three key figures in a decade of success, left for Arizona with no love lost for Dombrowski."
Once again the evidence strongly suggests that Henry and Werner decided not to renew DDs contract in the spring around April. Remember Henry said he was going to renew DDs contract in February well before ST had begun. The fact that he did not do so then is highly suggestive that Henry had no intention of renewing the contract.
Since the Sox did not make the playoffs means we will never know. But I think FO staff were so miserable and the work environment so toxic as I recall one Boston sportwriter putting it that Henry could no longer tolerate DDs leadership style.
