You keep banging the Lavarnway drum, but he could have hit his way into the MLB roster, but didn't. Deal with it.
Drew is playing because he's been excellent defensively and has provided some semblance of offense while WMB provides neither of. That's why he's at SS and Iglesias, who, with his superior defensive ability, was able to move around the diamond, is at third. That is the common sense move. You're just looking for an excuse to whine.
The Kalish point has been hammered into oblivion, and is a massive logical fallacy. Again, just whining for the sake of whining.
The important thing is what's currently happening, and as your above point proves it's been better. Under the current FO, this organization has never been shy in promoting positional prospects, and suggesting or stating otherwise is ridiculous. The problem is that they've coddled pitching prospects to the extent that it hurts their development. That point is absolutely true, but it's something that's improving at the organizational level as we see the aggressive promotion of pitching prospects this season, with Webster already making his debut, and RDLR soon to follow.
Isn't it all about "what have you done for me lately" anyway?
