^^^ Awesome sig.
You're going to have much better luck in the "Draft, Trade, Keeper and Waivers Questions" forum. Most of the "forum police" will haunt you until the end of time if you post trade questions in here.
Me personally, I would have a hard time selling off Sabathia right now. Yeah, you're probably selling him high, but you're also buying Magglio high. You can afford the trade, but I think I might try to get a little more. Solid pitching is a pretty good commodity and just because you have a bunch doesn't mean you should give it away cheaply.
