From this year's pitching staff, the only pitcher I would want back next year is Hernandez. But I expect Eovaldi back, and Perez is 50/50. Barnes is most likely dealt within a few days (otherwise he would be my second pitcher I'd want back).
Beyond that? Osich and Valdez have been tolerable. Brasier is probably back. Walden is probably back, but he's not the lock I would have suspected. Taylor? I'd trade him if I thought anyone would give me anything The rest? Cut.
Weber, Mazza, Hart, Brewer, Springs, Hall, Covey, and Stock cannot go fast enough IMO...
