UPDATE: Levine says it's Archer, Guyer, Lee, Chirinos, Sam Fuld for Garza, and a minor league outfielder and pitcher. I can't really evaluate the trade till we know the names the Cubs are getting.
Bruce Miles is reporting that the Cubs will send Chris Archer, Brandon Guyer, Hak-Ju Lee and Robinson Chirinos for Matt Garza, with possible other pieces still being involved. I realize as a fan of the Cubs I'm probably a little bias towards their own prospects, but that sounds like as good or better package than what the Royals just got for Zack Greinke.
Now I realize Greinke costs more than Garza at the moment, but in terms of talents, it's not even close. I suppose there's the worries over Greinke's social anxiety issues and whether he would approve a trade to the Cubs, but he seemed to just be interested in trying to win.
On the other hand, they're just prospects and only Archer and maybe Lee have much of a chance of being better than league average players. Folks and myself have freaked out before on trade packages including prospects to eventually discover those prospects end doing nothing. But man, it's quite the stomach punch if they do end up being good.
