Both were pretty bad trades, but it has to be the Raiders.
Its simple...at least ATL got a good young player with upside.
They still overpaid for Julio by an astronomical amount, but at least he has upside. But, still its an awful trade as well. Unless Julio turns out to be as good as Larry Fitzgerald...this will turn out to be a pretty bad trade. But, again...its better than getting Carson Palmer. At least they got someone who has decent value...with a good amount of upside.
The only way you should give up that amount of draft picks or more...for one player is if that one player is a young, stud franchise Qb for the future.
For instance...I didn't mind the Redskins trading for RGIII. It as a risky trade, but if RGIII turns out to be a legit, top 10 Qb in the game one day in the near future...It will be worth the risk IMO.
Trading that much for a Wr is not worth it unless that Wr has a chance to turn out to be as good as Larry Fitz, Calvin, or Andre. Anything less, and its just not worth all those picks IMO.
