I hated the idea of losing Lester. The lackey situation was complex, but once it became clear Lester was going to free agency, the purge was the right way to go.
I remember posting at the time, that people say "you have to fire the manager, because you can't fire the team," but we "fired the team" that summer.
My beef was that I had hoped we traded for younger players and top prospects and not Cespedes and Craig types. I had hopes for Kelly, and some of them are starting to pay off now, but the Yanks did better with their "purge", IMO.
