The firing of Alex Cora made the firing of Rob Thomson easier, if not a necessity. The Boston Red Sox and Philadelphia Phillies are cut from the same cloth: high-payroll teams off to disastrous starts facing April urgency with no avenues to change personnel.

Managers are fired in bunches. Like paper towels and pet food, scapegoats come in bulk. General managers like the cover of company when it comes to change.
