Not necessarily. While a Greinke injury would hurt his trade value it could also hurt his value on the open market in free agency depending on how long term the injury is. Other teams I'm sure would question his reliabliity and durability while it could result in the Brewers getting him at an affordable price now with an extension or during offseason negotiations. Sure, I might be overly optimistic here, but it's not all doom and gloom. Also, at worst, we will recieve draft compensation for Greinke if he leaves in free agency if teams start to low ball us on trade offers. I would hope Melvin wouldn't sell Greinke for pennies now that his value has lowered. He's smarter than that. Bottom line, as long as we get something of long term value - Prospect(s), High Draft choices, or Greinke himself returning to the Brewers with a long term contract agreement, this is not a Franchise Killer by any means and is an over reaction on your part because we didn't give up our franchise to obtain him. All we gave up was a solid but not great SS, a pot smoking reliever with a good arm, a nice pitching prospect that probably only projects in the middle of the rotation, and a solid but not great CF. If we had given up something more, I'd be more ticked as well.
