Re: What do all of the recent moves have in common?
I concur as well. This is just an old-fashioned house cleaning. The kind of guys who he's cycling through don't make or break an organization. But this organization has been so bloated, organizationally, with almost-prospect and veterans. It's one thing to bring 10 vets to camp and let them have it out. It's another when your AAA team is stocked full of 30 year olds who never made it.
Next offseason should be very interesting.
Games are won on run differential -- scoring more than your opponent. Runs are runs, scored or prevented they all count the same. Worry about scoring more and allowing fewer, not which positions contribute to which side of the equation or how "consistent" you are at your current level of performance.
