Erod, Cisneros, Lorenzen and Holten are good as gone in my estimation. I think the return will be minimal. Maybe one decent player for next year and a "platoon" major leaguer(s) and/or low minors guys.

Lange has damaged his value and Foley will require more than other teams are willing to pay since many free agent relievers like Cisnero will be cheap to acquire.
Trading Baez seems like an off season move and exchange for another poor contract.
