How about the current players on the Astros thank the heavens that they have a major league gig. Play for almost any other organization and you are in Double-A. Shut up and play ball.
Luhnow is a smart cat. I don't agree with the way alot of things are handled, but he manipulates the system and the Astros are going to benefit long term. Baseball is a business, and they run it like a business. They have amassed quite a bit of young talent and stand to do so again in the draft next year.
They may be better off with the 2nd pick in next year's draft than they would with Aiken. Kid turned down $5M with a gimp UCL. See how he fares in the draft next time he's eligible. Teams may be publicly blasting the Astros for balking on Aiken, but privately many are likely agreeing with the move.
