I'll try to break this down. Don't be super critical of the comparisons, they are to simplify the deal in my head.
Gordon/Coghlan are equal value.
Stubbs/Bills for Cargo is close at this point with Stubbs awesome and Cargo crap
Markakis/Cueto for Pence is highway robbery, you are getting hosed here.
On the whole it doesn't add up. You have one part equal, one part slightly in your favor, and one part majorly against you. An upgrade of either Cueto/Markakis is necessary for this to be a good deal.
Goldy is King.
