There's a good chance maybe only 1-2 prospects gained in those 3 trades I mentioned amount to significant net pluses. Maybe none do, but increasing the quantity and quality of the farm improves your odds.
I won't count the Betts trade that brought us Verdugo, Downs & Wong, and the deadline sell off of 2020, by definition is about the future (Pivetta, Seabold and some long shots), but let's look at the other 3 trades: Beni, Ottavino and JBJ:
Beni>
Cordero: Looking much better, this year and has 2 arb years left
Winckowski: .595 OPS Against in AAA- about as good as we could have expected.
Gambrell, de la Rosa & F Valdez: all long and far-away shots that have not wow'd anyone, yet.
Nothing>
Ottavino: gone
German: May be the best prospects of this whole group. .485 OPSA in AAA (5 IP)/.495 in AA (11.1 IP)
Renfroe (arguably obtained from the money saved by trading Beni)>
JBJ: High cost defensive whiz who seems to be improving his offense from 2021
Binelas: .813 OPS in A+ with 11 HRs in 160 ABs
Hamilton: .728 OPS in AA but dropping quickly
I like the odds we get something nice from 2, maybe 3, of these guys.
What JBJ, Cordero and Ottavino do or did might not matter, so much.
