trading herrera (wouldn't get much for hoch, so i discount trading him) only makes sense if you're getting something back that is more valuable that what you're paying for soria. with the way relievers are getting paid, i'm not sure that makes much sense. say you trade herrera for bradley jr. is that better than just keeping herrera and signing span or parra?
and, they'd still have to replace herrera with someone. hshd is a nice start to the relief squad, but they still need more bodies, and i'm not sure they have much in the minors that can fill in. maybe that aaa closer that was up in sept?
