I think the Brees Peterson trade is about as intriguing as it gets. I don't think you'd be an idiot for another trade w/improvement at another position too, I'd just be unlikely to give up either of those two in a keeper league. You're also tossing in a pretty decent DeAngelo Williams in the deal. He may not be a keeper, but you know either QB you're getting isn't either. I'd be more tempted by getting a great WR like Andre Johnson or something like that and fending for myself at QB. Simply put though, when you have a top 5 player in a keeper league it's always hard to justify trading him even for another top 5 player. The guy you're trading with obviously thinks he's getting the better end of the deal, right?
