There is one disconnect about Wren trading for Lohse. Are we really going to trade for him and his contract (22M over the next two year) when we weren't willing to pay Hudson what he got from the Giants (23M over two years)? I can see a case being made for Lohse being slightly preferable to Hudson, but not to the point where we are willing to give up a significant prospect(s) in addition to a salary that is about the same as what we would have paid to keep Hudson.
I don't see a disconnect at all. The Braves only valued Hudson at like 1 year and $8M, which is why he didn't resign. The Braves obviously think Lohse is a much better buy than Hudson.
