Usually I wouldn't answer this because I have a hard time giving up a great deal for a half season of some MVP type guy, so I might have a much different view than most others.
But RIJO is signed for another two seasons.
So whoever was "kind" enough to give you Iglesias, will get 2.5 yrs of MVP type performance for a guy that should NEVER be allowed to play SS. He could be a good defensive 3B, but what a terrible bat for a 3B. He is DONE developing. He MIGHT gain a point here and there occasionally, but for all intents and purposes he is as good as he is going to get.
I'd have at least given you two Iglesias type bench warmers for a 4 time MVP with a few seasons left in the tank.
