There's something to be said about your point, but this isn't an apples to apples comparrison. For one, Perkins is insanely cheap for a closer. He's basically signed on at a reasonable rate for a relief pitcher. As well, his final year is an option, so if by chance he flops, he can be cut free. I don't see Perkin's value possibly increasing over the offseason. He's been doing this proven closer thing for 2 seasons now and has been a dominant reliever for 3. His contract is very affordable too. My guess is that he hasn't been moved because no one wants to pay what Ryan wants for him.
