Interesting take. Hard to argue your logic on this. I agree.
I still think Beane is an outstanding GM, as well as exceptionally respected across the league. He's no dummy and he does everything he can to get the best team pieced together every year. The draft is a crapshoot but you still have to hit on your top rounds, which Beane obviously needs to strike more on. That being said, he's aggressive in free agency, and usually doesn't disappoint. Sometimes you get a little unlucky with certain signings and/or prospects. It's not from a lack of trying. We are blessed to have him, in my opinion.
