I think you have to offer arb to PK, Putz, and AJ. AJ is the only questionable one. Either you bring him back for 1 more year (and probably only that) at an inflated salary, or you get picks for him. And with our farm system, we really need the high picks. I think he will want a multiyear deal.
As much as Ive liked AJ in the past, Im hoping for the later. We need compensatory picks. It has really helped some of the successful org's.
