Edwin Jackson is not about to win the Cy Young award. Sorry.
Also, they traded him not because they needed money (although they do) but because in the future they wouldn't be able to afford him and wanted to get something for him while they could. Please don't talk to me about stupid trades, either- the Braves have written the book on them in the past decade, from trading a LEGIT Cy Young contender in Adam Wainwright and a serviceable middle of the rotation starter in Jason Marquis for a rental of JD Drew. Then, after not learning that lesson they traded a hot catching prospect, a guy who has turned out to be the best defensive SS in the AL, a future ML starter and a top reliever for Mark Teixeira, who when we learned that we couldn't sign him we traded for Casey Kotchman, who we thought so much of that we then traded him for Adam LaRoche.
