If they trade TA, they should prioritize pitching. Dodgers have three guys who are close -- Pepiot, Stone, and Miller. I would take any of those three. Gio would get you something. They should start shopping him now while he's still pitching well.
Internally, there's not a lot. I do not believe in Burke. Mena is very young, but he has plus control and pretty good command. I could see him coming fast. Cannon will be up by the end of next year. Don't know how much impact he'll have, though. Matthew Thompson is teasing that he may be a big leaguer. Under the radar lefties like Sommer and Murphy might be depth options by next year?
Other than that, you can count on a couple of scrap heap signings.
