it's not apples and oranges. First off Marte is 32 on the downslope of his prime years. Second he is owed a lot of money and I believe has 4 yrs left on that deal. You gotta think JH is telling Breslow to make sure AZ eats a lot of that $$. Finally given that Mayer was actually ranked #1 in his draft class I feel that if he can just stay healthy he can turn out as good as Marte and finally he is COST CONTROLLED for several years and you know JH knows that.
The last word on this is that I don't see Marte being enough to put us over the top right now in any event. But if we can get him for giving up an OF and aSP not named Bello, Early, Tolle or Crochet then yeah let's do it. But Mayer stays.
