Your analogy is close, but not exact.
It would be better if you said that a new owner buys a company where the manufacturing was good, but the sales team was bad. So he hires a new manager to fix the sales, but at the same time he takes the ax to the manufacturing side. Sales is fixed, but they're selling a crappy product. So a new manager is brought in to fix manufacturing, and he decides to axe the well performing sales team.
And I'm not ready to apply that analogy to the players' departure. But I will apply that analogy to McD's coaching choices in keeping Crossman, and adding Castillo & Rico.
