For good reasons. Neither players is "elite" (although definition of the word remains nebulous). And the "new owners" have only gone big once. For Tex (Horseface 1).
I don't see the Sox buying in on Crawford (my choice) for 6 years, much less 8 years.
As well, I don't see them giving Werth more than 4-5 years. From a business stand point, the cost would seem to out weigh the return.
