Come back with the cap argument next year, after they lock up Napoli and Kinsler, have to deal with a Hamilton extension, and arbitration raises. That 5-7.5 cap relief will look golden.
Also, there's this: According to scouts (and they could be wrong) Darvish was the best available pitcher this year, as in, better than Wilson. What if the scouts are right and Darvish is the real deal? The Rangers certainly think he is, and they're a model organization. So we, as fans, shouldn't rush to judgement on the investment until we see what happens. Next thing you know, he's an excellent pitcher, and the doubters look like fools.
That said, i'm glad the Sox passed on him. There's no middle ground here: Ace or bust.
