The Turner part makes it unbelievable, but Davis, Westbrook, Horton-Tucker, and Monk plus Bazemore would definitely get you Simmons, Harris, Green, and Thybulle plus Springer.
Philadelphia won't get a better offer.
Replacing Westbrook with Harris is a definite win.
Replacing Horton-Tucker with Thybulle is a win.
Replacing Monk with Green is a win.
Replacing Bazemore with Jaden Springer is a definite win.
It's the replacing Davis with Simmons part that makes it dicey. Davis is a better player right now, but I think Simmons under LeBron James' leadership will be better soon enough.
You lose size and shot blocking, but you gain defensive versatility, athleticism, reliability/availability, youth, ballhandling, and a clear-cut cornerstone who can carry your franchise five years from now when James hangs it up.
James with a good backup can play center fulltime. This notion makes me pull the trigger.
