Out of those 13, I think we keep these:
Barnes: pay him to pitch here not elsewhere, and hope he returns to 2018-2019 form (not early 2021.)
Downs: cut him some slack. Maybe missing 2020 hurt some guys more than others.
Hosmer: the guy is free and is better than Dalbec/Cordero, anyway.
Dalbec: still has options and until casas proves he's a keeper, we'll want to have more choices.
Not so sure:
Cordero; only because our OF depth is shallow
Kelly & Danish: only because our pen depth is shallow
Seabold: had good numbers in AAA and probably deserves a second chance
That leaves 5, Brasier, Almonte, Ort, Chang and Bazardo, which happens to be about how many players we will add to fill our 5 major need areas:
2B/SS
RF
SP
SP/RP
RP
If we add 6 or 7, we can find room.
The Paxton and Pham options weigh in on these numbers, too.
