In 2021, the Sixers traded Ben Simmons, Seth Curry and 2 firsts to the Nets in the following trade:

Sixer Receive: James Harden, Paul Millsap 2022 first with right to defer to 2023 2027 first (Top 8 protected)
Nets Receive: Ben Simmons, Seth Curry, Andre Drummond

That pick’s rights were deferred rights to 2023, and the Nets traded to Utah for Royce O’Neal; the Jazz drafted Brice Sensabaugh in 2023 with said pick.

Recently, the Sixers traded James Harden to the Clippers in the following 3-team deal:

Sixers Receive: Marcus Morris, Nicolas Batum, Robert Covington, KJ Martin 2026 & 2028 firsts from Clippers (unprotected) 2024 & 2029 seconds from Clippers
Clippers Receive: James Harden, PJ Tucker, Filip Petrusev
OKC Receive: Right to swap picks w/L.A.C. in 2027

Barring a further trade or team getting involved, the Sixers essentially traded Ben Simmons and Seth Curry for Marcus Morris, Nicolas Batum, Robert Covington, KJ Martin and two seconds while swapping their 2023/2027 picks (one of which is protected) for unprotected Clippers picks in 2026/28.
