Foulke is done, I really think that he just doesn't have it in him to be a dependable pitcher anymore, and Timlin as a closer? Thats your emergency option, not your first choice, I'd like Guardado, Eyre or Ryan to get signed to do those duties for a year, either that or use them as setup, these are bullpen pitchers, you don't HAVE to have them close if you sign them, they could get signed and be used as setup and have Hansen close if hes up to it. We need bullpen and the sox probably arent going to be too picky choosy about who they get and what their job is, they need guys who can stay healthy and get outs no matter what their role is.
Also, what would you get for a crappy and expensive keith foulke on the trade market? You can't just trade away guys you don't want and get things in return, I think that if foulke sucks this year, he'll get the big DFA.
