I just made a big trade, I need a serious opinion on my fantasy baseball team please....?

I like the deal. Dan Haren is is not doing that well right now, and you have plenty of SP depth to cover him. Juan Pierre is not hitting well right now (he may come around towards summer though), so no big loss. Morneau for Cantu is the biggest loss for you, but its definetly workable. You have enough depth in the outfield to cover for the loss of Morneau. And obviusly getting Franklin and Rivera are some of the best closers so you win there. Good trade.
