DD has much time to deal with Clay. My guess is another team would take a chance on him. When does the option have to be picked up?
Clay could be used in a package. How about Clay and Pomerance or E-Rod and Vasquez or Swihart for something better......... (just throwing names out there)
I know the reason most people don't like Clay is that he can be a burden to the rotation as he will probably be injured during a year, or maybe crap out. But you could also look at him as giving us some flexibility.. he's an interesting piece that could be used for value or just be valuable. Or he could crap out....
