Clogged up payroll in this case directly results in a clogged up roster. Do you seriously think that they would not want to move Sandoval or Castillo at this point? I am sure that they have tried to move both, but they would have to eat almost their entire contracts. I would not be surprised if they had also made every effort to move Hanley, but after last year's disaster, no one would want him. So, yes, I think the payroll clog has also clogged up the roster. Do we need a fat toad on the bench who is making $17.5 million? I'd rather have another utility type with a plus glove and some speed.
Edit: Plus, as far as I can see, Castillo has no role on this team. He is just taking up a spot.
