I'd say Clippard, Storen, H-Rod, and Burnett are locks barring a trade, but I think it is likely that at least one or two will be traded.
Coffey I think is gone, especially if there is a compensation / Type B supplemental pick we can get back for him.
Slaten may get pushed out, possibly by Severino. Severino shocked the heck out of me in September. Stammen I think may have one more option, so will start the year in the minors.
I suspect Balester hangs on as a long man. Mattheus may get sent down as a numbers / option victim. Gorzo I think re-signs, either after they refuse his option or a settlement before arbitration. Depending on rotation depth, Detwiler is either the 5th starter or the lefty long man.
So - Storen, Clippard, Burnett, H-Rod, two of Severino, Detwiler, and Gorzo, and Bally or Livo.
