I don’t know about the idea of anyone further compensating Washington for also making their 2030 GSW pick immensely better. They should just rush to approve the trade before GSW got any smarter.
What GSW can trade (bearing in mind Stepien):
2025 swap
2026 pick (or swap)
2027 pick (or swap)
2028 pick (or swap)
2029 swap
2031 swap
So they can trade two picks and four swaps. They also have some nice young players, but… yeah, IDK, seems pretty thin to me.
You can't just unprotect the pick...you have to take the pick back entirely. If you unprotect the pick, 29 and 31 cannot be traded. GSW must own 30 to make it work.
