Sixers should cut their losses at this point and just do the Powell, Morris, draft pick trade that the Clippers offered. Powell and Morris would actually be solid depth additions for the Sixers.
PG - Maxey, Beverley
SG - Powell, Melton, Springer
SF - Harris, Oubre, House
PF - Tucker, Morris, Green
C - Embiid, Reed, Bamba
Obviously Powell + Morris aren't as good as an engaged Harden, but they aren't getting that, so they should just cut bait and pick up some depth help. If Maxey emerges as a true #2, they might actually end up better with that team anyway
